NinyoonDM4 Digital Microscope with 4.3inch LCD Screen, 50-1000X Coin Microscope for Error Coins, USB Magnifier Micro Scope with High Stand 8 Adjustable LED Lights for Windows PC View

I’ve tried this microscope on various phones using its WiFi connection and various computers using USB, with the phones, it is excellent, easy to connect so long as you follow the instructions, remove the lens cover, (it's clear plastic so easy to forget), turn on microscope, connect to its WiFi then launch the WiFi check app. Connection is limited to one device at a time, I have tried it on Android 13, Android 9 and iOS 15.7.3 and it worked flawlessly, the zoom buttons and photo button on the microscope responded as they should, the image was sharp and it was easy to focus, here I will say that the supplied stand is poor and I would recommend getting a better stand, there are some available on Amazon and they do improve the ease of use of the microscope.Now to using it with a computer, first thing to mention is that you cannot connect to a computer using WiFi you have to use a USB cable, I tried the microscope on three windows 11 desktops, one windows 10 desktop and one windows 10 laptop, it worked okay on two of the windows 11 desktops and both the windows 10 computers, when connected to the other windows 11 desktop it caused the AMD graphics drivers to crash after a few minutes of use, the same AMD graphics drivers were on two of the other desktops that had no driver issues but all have different graphics cards, the highest end one being the one giving the problem, here I’ve got to say the support from the seller was excellent, emails were replied to within 24 hours and although no solution has been found yet the support is excellent. The reason I say it only worked okay on the computers is because the image had a tendency to freeze at regular intervals on all the windows systems I used, not a major issue if you're looking at coins or stamps and such like because changing the focus unfreezes the image until next time but not good if you’re going to be using it for soldering circuit boards, I tested them all using the windows camera app that is the recommended app to use. Another thing to bear in mind when using it connected to a computer is that the buttons on the microscope don’t work.Other things maybe worth a mention is that the USB lead is also used to charge the microscope battery, there is a wheel on the side to change the brightness of the light.To sum up, excellent for portable use, connecting by WiFi to a phone or tablet, okay for occasional use connected to a computer but if you’re going to be using it solely for connecting to a computer then I’d say get a USB microscope. Excellent and quick support available from the suppliers if it’s required.

I bought this 4K WiFi microscope after also previously purchasing a 2K wired microscope - both to be used with my Google Pixel 7 Android phone.The set up was very simple and took no time at all without any issues whatsoever, I charged the device for 2 hours as advised with a 5V 1A charger until the red LED turned off then downloaded the "WiFi Check" app from the Google Play app store. After holding the power button for a few seconds the microscope went into connection syncing mode and I connected to the microscope through my phone's WiFi settings and it was done.You open the "WiFi Check" app up whilst it's connected and can see on the screen what the microscope is being pointed at (take the lens protector cap off first), the focus wheel is really smooth and a big improvement from my previous 2K wired microscope model but the biggest standout feature to me was the image quality.The image quality looks so clear and sharp with plenty of detail for even the tiniest of objects and the clear plastic "cap" at the lens end of the scope allows you to actually stand the microscope up on a table or such hands-free with an object under it like a coin or tiny part of a plant without having to set up the provided stand and still get a stable view.This microscope works with Android, iPhone, PC and Mac which is a good news for many iPhone owners out there who couldn't use previous wired microscopes. The only downside is if you're using it with a computer the zoom function can be restricted but this wasn't an issue for me solely as a phone user.Overall I highly recommend this 4K microscope with the only downside to it being the provided metal stand which isn't very stable - but the seller also has a significantly better one for sale in their store for around £20 which I also own and is a massive improvement on the one provided.

First thing is first - this microscope is not wireless for a computer\laptop\etc, only a phone or tablet. it mentions this in the product description but I hadn't read it this until it arrived. For a computer you still need to use a cable. Don't make my "mistake". Having said that, as I'm mostly using an old tablet I'm happy with this microscope. I have one of the older wired versions of this. This wireless version with the tablet is much easier to set up and move. The wireless connection does use the tablet wifi connection, so not internet services whilst using it.The "magnification" control wheel it vastly improved. The grey rubber control goes round the entire casing as has a smooth operation. Once have the microscope at your preferred height it acts more as a focus. There are zoom buttons on the side to slightly zoom in\out if required. The build it led ring light is powerful but has an analogue brightness control wheel - better than the 3 brightness levels toggle on the old version I have. The picture is quite good for the price, but can still be a slightly grainy. I've not investigated the full 4k-ness of it to be honest.For the price point it is just the job for my occasional use and worth the extra £8 (at time of writing) over the wired version I have.
