TeckNet 2600DPI Bluetooth Wireless Mouse, 2600/2000/1600/1200/800DPI

excellent mouse great handling and i like the keys given on left worth for money

After a year, the scroll stop responding well..sometime down scrolling up..i bought HP gaming mouse to replace.Apart from scrolling issue, it's a good mouse

Very happy so far. Did not come with required 2 AAA batteries. Nice feel to it. Still a tad bit small for someone like me with large hands. Has a small vertical rise towards the back which helps somewhat on the large hands issue. Very nice mouse. Update: The mouse conserves the battery power by going into sleep mode, takes a second or two to wake up. Pretty annoying, havent found a way to turn off or adjust it. (when you complete a meeting and you want to disconnect it takes a few clicks to wake it up). I really want to turn this off completely.

muy buena calidad de acabados y material, ideal para el diseño arquitectónico, excelente ahorro de energía y muy cómodo al trabajar con el

Superb experience so far, perfect size for my hands and works well.

works great and good quality mouse

How it works:Operates with Bluetooth-enabled notebooks or PC without the need for a receiver (dongle). Enable Bluetooth on your PC, pair with the mouse, start working.Pros:- The TruWave technology does seem to work well over a variety of surfaces.- Operating distance was effective to about 20 feet.- Left, Right, Back, Forward buttons all work quickly and quietly.- The Scroll wheel is smooth and fairly quiet. Works well with no time lag.- Interesting feature: Holding down scroll wheel enables a Fast-Scrolling ability. An arrow appears on the screen, and if you move cursor above it, scrolls up quickly. Move below the arrow and it scrolls down quickly. The farther away from the arrow you place the cursor, the faster it scrolls.- Pressing DPI button cycles through 5 settings, reflected in the flashing LED 1 to 5 times- When you power off the mouse, then power back on, it connects to the PC immediately with no apparent time lag.- The User Manual recommends best results by using the mouse on a light colored surface. It seems just as responsive & quick on a black colored mouse pad; although the manual suggests that may decrease battery life.- It comes with an 18 month warranty that may be extended to 24 months by registering the device at the TeckNet website. Did that, and it was an easy process of a few simple steps.Cons:- Usage the next day (after it’s been sleeping quite a while) shows a bit of initial time lag between button clicks and the actual response by the PC. (Can't determine if caused by the mouse or the PC). However, movement of the cursor by moving the mouse around is always quick.- I evaluated the BT mouse on two different PCs, both running Windows 10. One of the PCs performed well with the BT mouse. However, I did encounter one significant problem that is most likely related to the 2nd PC’s Intel Dual Band Wireless-AC 3165 chip itself, or the Firmware & Drivers; but I'd be negligent if I didn't mention it.BACKGROUND: With other (2.4 GHz & receiver/dongle) mice, my 2nd PC’s Wi-Fi varied between 135-150 Mbps. But the moment I turn on the BM307 (and it quickly pairs with PC & comes alive), the Wi-Fi drops quickly to 54 Mbps, then 11 Mbps, and often loses connection to the router completely! (Even while connected, the browser can't seem to find anything on the internet.) I do NOT believe this is the BT mouse's fault; more likely, Windows-10 is having trouble driving the Intel Pro-Set combined Wi-Fi & Bluetooth single chip. When I turn the mouse off, Wi-Fi remains at 54 Mbps until I ran the Win-10 Troubleshooter... Nothing showed up against the Wi-Fi circuit, but it found something wrong with Bluetooth, repaired it (in the background), and my Wi-Fi connection immediately shoots back up to 135-150 Mbps while the BT mouse was asleep. The moment I clicked a mouse button to activate it, the Wi-Fi dropped immediately to 54 Mbps, then to 36 Mbps! I had do Disconnect / Reconnect to the Wi-Fi to get 150 Mbps back. I updated the Intel DBW-AC 3165 drivers to the most recent ones (dated 5/29/17) and resulted in no change! Bottom line: The BT mouse worked well with the 1st PC; and only the 2nd PC had Wi-Fi slowdown problems when using the BT mouse. Your mileage may vary.Overall Evaluation:- A good quality responsive BT enabled mouse of slightly smaller size. Convenient for travel, but big enough for everyday comfort. Shares the same physical mouse unit/body as their 2.4 GHz mouse (as shown in the comparison photo).- Requires 2 x AAA batteries (not included). Box contains the mouse and User Manual. On/Off switch on the bottom.- The optical sensor on the TechNet standard 2.4 GHz mouse (same device body but with receiver/dongle rather than BT circuitry) does not reveal visible light beneath. However, the tBM307 always reveals the red LED (or LASER?) constantly glowing. No concerns, just FYI that it’s normal.- FYI, to enable the PC Windows 10 side, try this: - Click the Start menu and select Settings. - Click Devices. - Click Bluetooth. - Move the Bluetooth toggle to the desired setting. - Click the X in the top right corner to save the changes and close the settings window.- FYI, to enable the BT mouse side, try this: - Press button on mouse bottom 2-3 sec to enable the pairing mode - on the PC, Click "Add Bluetooth or other device" - After about 10 seconds you should see , "TeckNet BM307 Connected"
