Keychron M3 Wireless Gaming Optical Mouse, Tri-Mode 2.4 GHz/Bluetooth 5.1/Wired, PixArt PAW 3395 Sensor, 4000Hz Polling Rate, 79g Lightweight Programmable Macro Button for Windows PC/Mac - Black

I picked the M3 4K up to replace a dying Logitech MX518. I have a keyboard from Keychron and love it, so it made some sense to try their mouse. After using it for a while for general computing and gaming, I've decided it's a keeper. My hands are on the larger size, hence the 518, and this one is smaller. It is lighter so it's easy to move with your finger tips and my hands haven't cramped. Build quality is solid with no creaking or cheap plastic feel. All buttons click nicely albeit loudly. I will say that the mouse wheel performs very well with a rubber outer layer so your finger tip has excellent grip. It spins easily and clicks into place naturally. Pressing it down feels good and solid without worrying if the wheel is going to roll. Upon moving the mouse, waking it from sleeping, the mouse wheel will briefly light up green or red indicating the charge of the battery. The mouse wheel is probably my favorite thing about it considering it was my biggest worry when ordering sight unseen. Keychron got it right. Connectivity is great so far using the 2.4GHz wireless connection to take advantage of the 4K polling rate. I have not used BT. It charges quickly and holds a charge for days of heavy use. In case your didn't find it clear, the little keyboard receiver connects via USB to your PC. If you keep it close to your mouse, you can unplug the USB cable from the receiver and plug it into the front of your mouse to charge it. So, does the 4K polling make a difference? Yes it does. It's minor, but it is noticeable. The mouse pointer moves a little more smoothly and that translates to better accuracy. It probably won't change your life, but it will add to it a little bit.

When I purchased this mouse, I never could've expected how good the software for it would be. You can control the mouse in full from any chromium based browser. The connection options are unmatched in this price range and I would suggest this mouse to especially laptop users.

Very good you can change the lights and have different actions for the buttons. Build quality is good.

This is a very lightweight and responsive mouse. Setting it up is a breeze. Just plug the dongle into your usb port and press the button. Buttons are quite responsive and have a satisfactory click. The scroll wheel is quick and adjustable so whatever speed works for you is just a few taps away. This mouse is replacing my Logitech that was double the price and it performs exceptionally better.

If you have a macbook pro, this mouse is absolutley amazing. It fixes the latency problem and is very fast and responsive. It's perfect!

Mouse is probably fine, but its not ok to resell used mice. Someone else clearly used this device before it was sold to me. It has fingerprints all over the box, no packaging in the box and the mouse already has wear spots on the buttons. This is not acceptable.

This mouse works great on bluetooth and via usb dongle. USB-A and USB-C dongles are included. The only thing I ding this mouse for, and it's a big deal to me, is no place to store the dongle in/on the mouse, so you're sure to lose it if you use it via Bluetooth most of the time, but occasionally need to use the dongle.

The reason I purchased Keychron Mouse was because I was purchasing a Keychron Keyboard. The main reason for the purchase of the Keychron Mouse and Keyboard is that both support RGB light mode IE the mouse and keyboard cycle through a variety of colors over a period of about 5 seconds. I'm happy with the purchase and would recomment the Keychron products. Note that I'm using the mouse and keyboard in wired USB mode. I did not try and have no desire for Bluetooth or other wireless modes supported by the Keychron products. Also note that I'm using the Keycron Mouse and Keyboard with a Apple M1 powered Mac Mini desktop system.
