Logitech Performance MX Wireless Mouse (Discontinued and Replaced by MX Master 2S)

My initial experience with a Logitech Performance MX mouse. First thing, it is a mouse for the right hand. Whose right hand I asked myself, surely not MY right hand. I wondered if the hand that it was designed for was an alien, with absurdly long triple jointed fingers and an unusually shaped palm attached to an arm that swept horizontally at an odd angle. I continued to gripe and complain to myself until the phone rang and I tended to business. Several minutes later I found myself back at the keyboard and mouse and realized that I had transitioned to the new mouse without thought. Yes definitely some alien brain manipulating handiwork here. To install it, I put the rechargeable NiMH AA battery into the battery compartment. The battery included didn't impress me much and it was also completely uncharged so I put in a better class of battery that I happened to have at hand. I did notice that the charger cord had a nicely sculpted 'grip' on it. That was a nice touch, along with the faux-leather pouch to contain the accessories: charger, charger cable and receiver extension cord. I was happy to see that the battery compartment has room to hold the *tiny* USB dongle that plugs into the PC and provides the wireless receiver. The 'UNIFYING' technology allows one single dongle to server multiple Logitech devices. As I already had an existing Logitech device and a dongle, I didn't bother to put it into the PC, I just left it in the mouse battery compartment and was happy that it had a safe place where it wouldn't get lost. The Logitech setpoint utility was already installed on my Windows 7 PC at work and it recognized the Performance MX right away. I noticed that *unlike* some other mice that need to be 'woken up' and discard the first few mouse movements, the Performance Mouse is instantly responsive. Maybe that is the 'performance' part along with the 1500dpi resolution and darkfield dual optic sensing. The mouse tracks smoothly and reliably. I was surprised that the extra buttons were well placed and not subject to unintentional activation. I had myself unintentionally become accustomed to the mouse in a short time. I used the mouse for the rest of the day, and before leaving work I packed it up to take home. After packing up the MX, I put my original mouse back on the desk and was shocked at how... dull and unresponsive the old mouse felt. The MX mouse installed into Windows 8 at home without a problem, and again was nice to use. The Logitech setpoint software running in windows 8 has some options that work differently than when it is run in windows 7. For example, the ability to assign window flip/ aero flip/ application switcher doesn't seem to work on Windows 8 when assigned to one of the additional buttons. I haven't contacted Logitech about this. In the end, I really like this mouse, it works well, it is cordless, responsive and comfortable. I might even get another one for work. It is a really nice mouse. Follow-up: since my initial review on January 4, 2013 it is 9 months later (Oct. 2013) and I'm still using this mouse. It is still a bit large for me and I tried a very similar styled 'marathon mouse' for smaller hands for a while but it just didn't perform as well. This performance mouse needs a recharge every couple of weeks but it is easy to recharge it by plugging in the USB cable. This mouse can be used while recharging, or left plugged in overnight. The mouse has held up well after lots of use, many hours a day with minimal signs of wear, a bit of shine on the left mouse button press area but all other parts showing no obvious signs of wear. The teflon slider pads are ample and in place. Best thing about this mouse: it tracks well, every button click registers when it should and it is responsive. Still a really nice mouse.

I've been a fan of Logitech since I bought my first mouse and keyboard from them (MX3100). Since then they have continued to keep my interest (and my patronage) by constantly developing new and innovative products. The dependable quality of Logitech devices has been the main reason I stick with them and the new Performance MX Mouse continues this trust. I wasn't sure if this mouse could hold a candle next to my beloved MX-1000, which had finally retired itself with a worn down right-click button. However, the Performance MX surprised me. Ergonomics: The first thing I noticed was the comfort - this mouse fits like a glove in my hand and it's so light it feels like I'm moving a cloud around. The rubberized thumb rest is just that; an excellent resting place for my thumb. My fingers do not get cramped or ache even after hours of use, and I should know about this since I'm an illustrator and spend many hours on the computer. Great Features: I wasn't fond of the scroll wheel placement on the Revolution, but with the Performance MX this has been replaced by two Back and Forward buttons. An awesome feature for me because I'm constantly going back and forth on web pages checking out my work. Right below these buttons is a single Zoom button, which I changed in the settings to refresh the page (Ctrl+F5). On the very bottom of the rubberized thumb rest area is a small icon, which I did not see at first and so when I inadvertently pressed down on this all my open programs and windows zoomed out and I was like 'Woah!' I could now pick whichever window I wanted by clicking on it and it would zoom back in to normal size. This is a great feature! The main scroll wheel on the top can move like greased lightening, but since I'm old school I preferred the simple click-click scroll of the older mouse. Thankfully Logitech must have some old-fashioned nerdiness in them, too, because you can press the small button behind the scroll wheel and it turns into the click-click function I love. Kupo! Having an On-Off switch on the bottom is a must for any cordless mouse and naturally the Performance MX has one. Unifying Receiver: I was really impressed with this new innovation. Not only is this thing tiny but it will work with all my wireless devices (negating the hassle of using multiple USB receivers). I have an old Logitech MX3100 keyboard and it worked without even a hiccup once I plugged the receiver in. It's also nice to have the receiver out of the way and not sticking out of the front of my PC's IO port. I just used a Logitech USB extender I had lying around, plugged it in, and have it sitting on the back of my computer desk. Nice and neat. Battery: At first I was a bit puzzled about the little black leather bag that came with the mouse. Not being one to read the manual it took me a few minutes to figure out that it contained the "extras" - a new slimmer version of the USB extender, a nice long USB cord, and the square plug that fits into the wall outlet. I thought it was a nice touch on Logitech's part to put these extras in their own little zippered bag. The battery in the mouse lasts about as long as the one in my old MX-1000 did. And since it takes AA rechargeables I can use my Eneloops with it as well. This is an exellent plus in my book because now there won't be any issues with the battery dying and me not being able to replace it because it's part of the mouse. I also like how you can still use the mouse while it's plugged into the wall charging. As always Logitech's presentation and packaging of their products gets kudos in my book. You don't need to be Superman to rip the thing out of some plastic cocoon; the box comes with a very easy to open lid and you can even keep the box to store the mouse in (if you so desire). All in all I believe Logitech has created their own version of the Mighty Mouse here (at least for us non-Mac users) and I can't recommend it enough. I know the price is a bit more than other wireless mice, but you're getting the Logitech brand and quality and the Performance MX more than lives up to it's price tag.

What an excellent mouse. I've been using this mouse at work now for over a year. I love it. The mouse is heavy. Perfect. The feel is smooth and it just feels like quality. The battery life on this mouse is a bit disappointing. When I originally got the mouse I found that the battery might last 6 or so days. So you would start on Monday and get a low batter warning next Monday. This is assuming you don't use the mouse on the weekend like I did since this was used at work. I turned the mouse off everyday before leaving the office. But battery life was way below the 1 month Logitech mentioned. I did reach out to them and they did replace the mouse. I noticed the replacement mouse had an Eneloop battery. The old mouse had a different battery, I can't remember the manufacturer but it was not an Eneloop. Battery life was better in this case. Roughly 3 weeks but still below the 1 month I hoped for. I didn't bother Logitech about this because the mouse is excellent. I usually let it charge between lunch breaks so charging times weren't an issue. I cannot stress how amazing the scroll wheel is on this mouse. I now expect that any mouse I use can scroll like this one. I can switch from regular speed scrolling to super fast inertial scrolling at the press of a button. I don't coddle this mouse when using the button either. I just press it when I want to stop. Still works great. I loved this mouse so much that I got another one for home use. It's the standard I have for mice. My work mouse has a small grease spot from my index finger sitting on the same spot for over a year. And the logitech logo on the back of the mouse is fading. I look at that stuff with pride. This is a work mouse and it is excellent. I'm happy it works on glass. It is another feature I expect from mice. The forward and backward buttons are the buttons I use the most besides the obvious ones. I did program the Application switch button to the Start Menu for use with Windows 8. The mouse works great. I use it primarily in Windows but also use it on my Mac. I can't speak for how this mouse compare with the old MX because I did not have one. But I do recommend it whenever possible.

The only reason I gave this mouse 4 stars instead of 5 stars is because of the price. The manufacturers suggested retail price of $80.00 (plus tax, free shipping with Amazon) is way too expensive for a mouse regardless of its functionality. I purchased the Logitech Wireless Performance Mouse MX for PC from Amazon and I have been using daily since July 1, 2011 (about 10 days now). I pre-ordered the Logitech Wireless MX Revolution way back in early 2006 and it was the best mouse I ever owned. I loved it so much that I disassembled the mouse to replace its battery with a new one when the old battery no longer accepted a charge (the old battery lasted until October 2010). I really loved that mouse. My nephews were playing near the pc and leaned into the wireless USB receiver that came with the MX Revolution and cracked it, so the MS Revolution was no longer detected by my pc. That receiver is about one and one-half inches long and really stuck out from the pc. I looked for a replacement for the receiver on the internet when I considered the newer Logitech Wireless Performance Mouse MX. I was aware of the Logitech Wireless Performance Mouse MX from when it was first released but I never considered it because I loved my MX Revolution and because some reviews made the Performance MX sound like something I might not enjoy. In fact, after 10 days of ownership I find little to substantiate those negative reviews. The Performance MX mouse is superb and does all that the MX Revolution did. I do not use CAD software so I cannot comment on how the Performance MX applies there, but I use Microsoft Word, Publisher, and Excel and Adobe Photoshop and Illustrator, and Mozilla Firefox on a near daily basis. The Performance MX is wonderful in those applications, as if I never changed my mouse. Here were my concerns before purchasing the Performance MX: "One-Touch Search" and "Application Switcher" buttons. With the MX Revolution I used the "One-Touch Search" and "Application Switcher" buttons constantly. The MX Revolution had a button on the top just below the wheel that served as the One-Touch Search button. That button on the Performance MX is now a "gear shifter" that changes the wheel from click-to-click like a standard mouse wheel to a wheel that spins freely so that you can move up and down long pages quickly. I never used the freely spinning wheel feature on the MX Revolution anyway because I use a Firefox add-on called FireGestures which is far more useful and efficient for my purposes. However, the Performance MX has a button just below the forward-back thumb buttons (it is labeled as the Zoom button - a useless feature) that I easily reconfigured via the SetPoint software to be the One-Touch Search button. I spend several hours per week browsing the web with Firefox and I use the "One-Touch Search" feature of the mouse very heavily - I am constantly highlighting the name of a file in Windows Explorer or some text in Word or some text on a webpage, and I simply press the "One-Touch Search" button on the mouse which automatically opens a new tab in Firefox and performs a Google search of the highlighted text. That feature is crucial to me and the Performance MX does it well. The Application Switcher was actually a thumb-wheel on the MX Revolution - a wheel the Performance MX does not have., However, the Performance MX has a button in a location that the MX Revolution did not have - the thumb-rest area of the Performance MX is a button. You actually press down on the black rubbery area. The photos of the Performance MX shows what looks like a tiny button with little white boxes on the thumb rest area. That little thing is not actually the button - the entire area is. Ergonomically, the Performance MX is slightly larger than the MX Revolution. I have a very large hand so I really appreciate the added size, as slight as the increase is. The Performance MX feels slightly lighter too. To nitpick, the little button below the forward-back button could have protruded a bit more to give a greater tactile feel to its location. The wheel is angled towards the index finger. It is not perpendicular to desk top, but perhaps on a 75 degree angle. While that angle makes for easy and comfortable wheel scrolling it took some time to adjust to clicking the wheel since the wheel needs to be pressed in at that 75 degree angle. Nitpicking over. The texture of the Performance MX feels indistinguishable from the MX Revolution. The Performance MX's tiny Unifying Receiver is a great upgrade over the long and protruding receiver of the MX Revolution. The Performance MX uses an easily replaceable 1900 mAh AA NiMH rechargeable battery - which comes included in the packaging - and this too is a great upgrade over the not-meant-to-be-replaced battery of the MX Revolution. Also included is a rubberized pouch with zipper to hold the USB extender cable (in case you want to place the little Unifying Receiver right on your desktop), and a USB-to-Micro-USB cable and a USB-to-wall-outlet adapter to recharge the mouse. The USB-to-Micro-USB cable can also be used directly plugged into a USB slot on the pc to recharge the mouse. Recharging can be performed while using the mouse like a wired mouse in that fashion. I charged the mouse overnight when I received it 10 days ago and I haven't had to recharge it yet, although the battery indicator is showing almost no charge right now. Inside the battery compartment there is a small compartment meant to hold the Unifying Receiver for transportation. So you pop the Unifying Receiver in that compartment, pop the mouse into the case with the recharging cable, and you can take your mouse to work on a different computer. I use the Performance MX on a 12 inch cloth-over-rubber SteelSeries QcK Gaming Mouse Pad which you can find here on Amazon for about $10. The mouse glides perfectly across the surface and my wrist really appreciates the ultra-thin pad. I bought that mouse pad for the MX Revolution because that mouse worked erratically if used directly on wood laminate and on the plastic glossy mouse pad that comes with Dell computers. The Performance MX seems to work just fine regardless of the surface. I've even used the mouse on my pant leg, the arm of my chair, and the top of the computer tower for brief moments and the Performance MX worked just fine. Overall, I am extremely pleased with my Performance MX mouse and I consider it a very worthy successor to the MX Revolution.

I was looking for a wireless mouse for my mac, and could not find the right one for quite some time. Finally, after deciding to spend the money, I found the best mouse I have ever used. The mouse is definitely worth the money!! It was so worth the price because I know I will never have to worry about being a replacement for this mouse for a long time! PROS- 1. PAGE FORWARD/BACKWARD- The 2 buttons above where your thumb would go are for going back and forth between different web pages. The allows for super quick web surfing and saves a lot of time. It took me a while to gets accustom to these buttons because they have not been on any other mouse I have even bought. But, I find myself using them constantly. 2. ZOOM. Below the page forward/backward button, there is a zoom in and out button. You just push it in and use the scroll ball to find the perfect zoom. Definitely a cool feature. 3. ALL DOC. The black pad where you thumb would go can be pressed in to show you all your current documents that are open. This is a great feature because if you have the internet open, word, and some other documents, it can be annoying constantly searching for what document you need to pull open. When you press this button in, all your open documents will space out on your screen and you can pick which document you want to be looking at. 4. SCROLL. The button below the scroll ball can be pressed in to allow 2 different speeds of document/website scrolling. The first speed is a slower to normal speed that must of us are used to. The second speed pretty fast. This is like a hyper scroll that allows for fast web browsing. Pair this scroll speed with the page forward/backward button and you got a web searching monster mouse! 5. SIZE. Possibly my favorite thing about this mouse. Every mouse I have used before has felt too small in my hand. The mouse is the perfect mouse, as my palm and sausage fingers fit perfectly on it. This mouse just feels like your hand should be on it. The design of the mouse is awesome great. There is a great slot to rest your thumb in, which allows for maximum comfortably and control. CONS- 1. PRICE. This mouse may be a little expensive as it is around 75 bucks. But I feel like the price is actually pretty good for what you get. The MX is definitely worth the price. I believe this mouse compares to other performance mouse's that cost 100 plus. I would highly recommend this mouse to anyone that is willing to spend the extra money. This will be the last replacement mouse I ever buy because it is just perfect! Great for someone with bigger hands! It is so comfortable and document/website friendly that will not disappoint you. This mouse holds a charge for a long time. I have had the mouse for about 6 months and probably only charged it twice (using my computer atleast 10 hours a weeks). Try this mouse, you will be glad you spent the extra bucks!

I have been using this mouse for a week now and have not yet needed to charge the battery. I am 32 years old and work in an office. I have a laptop docking station at the office and use my laptop at home. I have been using this mouse a lot. 8 hours at work and about another 2 hours at home every day. I have used about 1/3 of the battery. This mouse uses rechargeable batteries and it is very smooth and comfortable in your hand. The page scroll wheel on top is very fast. It has a button you can click to change from a click based scroll like on a normal mouse or a smooth scroll, smooth scroll is like a wheel that keeps spinning and spinning. You can scroll down about 1200 lines of an excel spreadsheet when it is on smooth scroll. The only downside is I keep my two fingers on the left/right mouse buttons and I will bump the scroll wheel with it and it will move my place on a page. I normally always keep it on the click scroll, but the click scroll will still scroll through documents quickly just not as fast. You can also set up the buttons and customize then anyway you want to. The back forward buttons on the side of the mouse are really neat, I changed my setting to control my volume up and down since I am not really used to clicking a mouse to go back while on the internet. It also has a button where the bottom of your right thumb would be, I have it set to open all apps, like internet, excel and word and you can see everything you have open that way. You can even customize the left and right scroll wheel, what I did is if I am in excel and I have columns that are further to the right off the page I can click the scroll wheel to the right, just give it a little push to the right and it will scroll further to the right on my documents, the I can hit it to the left and it will scroll to the left, then I can roll the wheel down to go further down my document. It really is impressive having the ability to scroll up, down, left or right. Also you can customize the mouse ever further, you can make it app specific. You can set up certain functions for when you are just in excel or word or in outlook. You can have the clicks all do three different things depending on what program you have open. One thing I have set up in outlook is if I get an email and I want to google something that was emailed to me. All I have to do is highlight the word or words and click in the scroll wheel and my internet opens up to google with whatever I had highlighted being searched, yeah it is pretty awesome. It really is well built and you get every penny out of this, I did see some negative battery reviews on here and I have to tell you just dont believe them. The battery life is amazing. I feel like I will make it 3 weeks without a charge, and a full charge should only take 2-3 hours and you can still use the mouse while it is charging. Also I am a gamer, and this mouse is great for games. I think the weight of it is perfect, it works great for all those first person shooters. In closing I would say if you have the money and you are thinking about it, just buy it. You wont find a better mouse, whether you are a office employee or a web surfer or a gamer you will love it. Battery life is fantastic, everything about this mouse is amazing and to think it is just a wireless mouse. It really has changed the way I work and made things al ot easier on me.

UPDATE: When I upgraded to Win 7 (from XP), the mouse scroll and buttons became laggy, same with my logitech BT keyboard. It was due to logitech "Setpoint" software, this thing does not work well win Win 7, but it was flawless with XP. I went to this link, ftp://ftp.logitech.com/pub/techsupport/mouse/, to download an older setpoint version, file setpoint632_x64.exe. Installing this older version makes the mouse wheel work much better, scrolling in webpages is instant now, and side scrolling is still a big laggy using the back/fwd buttoms (I remapped), but better than when you use the most up to date setpoint, close to ideal. I'd give it 3.5 stars due to all this, though I still blame Win 7 just as much, I'm one of the few I guess that much prefer XP (and Office 2010 for that matter). I use the keyboard as much as possible when in excel or any program for that matter and liked my previous lenovo BT mouse that was very small and worked flawlessly, very responsive, but this mouse is outstanding. One of the best things about my prior mouse was it's small footprint but not feeling like a micro mouse or something for just travel, but doubling for that perfectly as well. I much prefer the size (very comfortable to hold, I'm tall/big hands) and heft to this, not that it's that heavy but it feels very solid, moving a greased up brick. Excellent responsiveness and settings so you can customize it to almost any extent - acceleration, DPI, pointer speed, etc. I use 2 monitors (will get 3 eventually) and while I don't use the mouse a ton, when I do I want it to be very quick & precise, which this is. One of the best things about this - just excellent mouse, it's not something like a cell phone that has good bells & whistles but poor call quality. Exact opposite here. Then on top, it has all sorts of buttons for customization (for all programs or program specific) and say 80% of them are very useful, you don't notice the ones that don't quite pan out. I also use a logitech BT keyboard and they both paired and work off the same tiny BT adapter flawlessly, it automatically suggested I do when I started using it and ran me thru it in 2 mins, no prompting from me. Wheel: Very fluid, I prefer the setting where it still clicks (quick button on the top that switches back & forth), though you can make it basically zero friction too, which I sort of prefer but you lose all precision and often times it is still scrolling long after I've stopped moving the wheel, which is worthless and simply doesn't work in excel, though tolerable for web pages and the like. The wheel also is a button, I use it to switch between the mouse DPI settings for now (default), will probably make it my home folder or something in the future. Wheel - Side scroll / Arrows, Zoom Buttons, and the rest: The side scroll feature by tilting the mouse wheel left and right I don't use, I made the arrows on the left of the mouse scroll sideways because I just don't have the force to quickly push my index finger left and right like that (2 surgeries on knuckle for that, but it'd be awkward without that still), it's much quicker using the arrows. Then I make the zoom button my back button since I don't really need the zoom and it's all the same. I don't use the massive multi task button that your thumb rests on but it's kind of neat, just like an extra option for a button if you want it while not detracting from the basic mouse function.

I've got some mixed feelings about this mouse. it's a pretty good mouse, and I really haven't found anything out there that I like better. But every great feature is slightly tarnished by a goofy design choice or avoidable flaw. So for half of MSRP, I'd buy it again. But full or even 3/4 of MSRP? The flaws are enough to make me pass on it. The mouse itself feels great. I've always preferred asymmetrical mice, and this one is amazingly comfortable. I've many different mice over the years, most recently the the Logitech M705, G400, M505, and the MX 518, and this one feels the best of them all. That being said, some of the thumb buttons are unreachable, hence useless, from a standard grip. The forward button is so far forward on the mouse that my thumb would need to be an inch longer to use it. I don't use most of those buttons (except the application switcher, which is both reachable and helpful) and so this doesn't really affect me, but you may feel differently. The best feature on this mouse is the Hyper-Fast scroll wheel. Hyper-Fast scrolling is the best thing to happen to scrolling since the scroll wheel itself. Need to get through hundreds of pages or thousands of rows in a spreadsheet? The old way was scroll-scroll-scroll-scroll-rest finger-scroll-scroll-scroll. With the Hyper-fast wheel, one quick flick and it will keep scrolling at a blazing speed until stopped. With one spin I was able to move through 6000 rows in Excel in under 10 seconds. If you want to turn off hyperscrolling then you can click the button on the top to turn it back to a normal scroll wheel. Personally I leave it on all the time and use my finger as a "brake" when needed. But even hyperscrolling is not without flaws. With Smooth Scrolling enabled, the page had a tendency to jump around quite a bit. The scrolling seemed inconsistent; sometimes it stopped in the right place, other times it didn't, other times it seemed to scroll on it's own. It was anything but smooth. I've had this problem on two different computers with both this mouse and the M705 (another hyper-fast scroll mouse) on several computers. At the suggestion of the Logitech forums, I switched it off in the Logitech SetPoint settings, which seemed to resolve the problem. The most awful part of this mouse is the battery. My M705 is still running on the same batteries I put in two years ago. It currently sits in my desk drawer because the rechargable battery in this unit dies - WITHOUT WARNING - every !#@$^! few days. The low-battery warning that appears on the screen with every other wireless logitech mouse or keyboard I've ever used doesn't seem to work with this mouse. It does have a low battery indicator on the mouse, which is <sarcasm> very helpful </sarcasm> considering it's located right below the palm of my hand. The battery life on this thing is terrible, as is the recharge time. The cord isn't long enough for me to use the mouse while it's charging, so I keep my old trusty M705 in my desk to use while this one charges. The M705 is basically my Monday/Thursday mouse. For fifty bucks (sale), I'm living with the flaws and would probably buy it again. It honestly feels great in the hand, much better than the smaller m705, and those are the only two options that Logitech offers right now for wireless, contoured mice with the Hyper-fast option.

これより新しいMX MASTERが出ているが、持ちにくいので、左手用のサブ機にしかならなかった。仕事で一日中持っているので、このマウスが最高に操作しやすいし、違和感や疲れが少ない。

Entrega: Rápida, confiable, segura, el pedido me llego antes de lo esperado y en buen estado, gracias. Opinión: Es un excelente mouse, un poco grande a lo esperado (pero los botones son grandes, si eres de mano pequeña aun así te servirá) tiene muchas funciones a programar para su uso (descarguen el programa de la pagina oficial logitech), lo recomiendo al 100% para aquellas personas que se dedican a trabajar en diseño, programación o están todo el día en la computadora, es muy confortable y ergonómico (tu mano y muñeca te lo agradecerán), cumple con todo lo que promete en las reviews que dan. Aparte los materiales se ven resistentes y elegantes, así que no solo es funcional si no también impresiona con su aspecto.

Darkfield sensor allows you to use the mouse on any surface, I am using it on fully transparent glass table. It's a good mouse for users who use mouse for cursor control. Forward button may be little difficult to reach for someone with short thumb. Some reviews have mentioned mouse double clicks with a single click but have not noticed that as yet on mine.

La souris Logitech MX est tout simplement géniale. Elle offre une excellente prise en main et est très confortables. Les touches raccourcis sont parfaitement positionnées et facilement reconfigurables au besoin. La souris est très précise autant sur un tapis de "Gamer", une planche de mélamine ou sur la jambe de l'utilisateur. Je l'utilise régulièrement pour des présentations debout et je peux interagir sur l'écran en glissant simplement la souris sur ma cuisse et sa fonctionne parfaitement. Sa forme offre une prise ferme permettant son utilisation en se déplaçant sans risque de l'échapper. Elle est excellente autant pour le travail de bureau quotidien que pour le "shooter gaming". Je la recharge environ une fois par semaine en la laissant allumé toute la journée et l'utilisant environ 4 heures par jours. Sa prise de recharge permet l'utilisation sans contrainte lorsque le fils est branché. Je recommande absolument cette souris de qualité à tous. Livraison rapide avec Amazon Prime.

購入して約１３年、もう外見はボロボロですがいまだに愛用しています。 性能といい大きさといい文句のつけようがありません。 最近接触が悪くなってきていますが一応一個だけ予備を所持しています。 後継機種があるそうですが全くの別物でがっかりしました。 なのでそのストックも開けるのがもったいないくらいです。
