Wheel issue

I wanted to love this mouse, but both M3 and M3 mini have the same irritating bug - wheel randomly scrolls in opposite direction.

Really happy with this mouse

Finding myself always reaching for my 2.4GHz travel mouse because my regular mouse's bluetooth connection was balky and intermittent, I realized it was time to buy a quality non-bluetooth 2.4GHz mouse.

I'm not a gamer, so the idea of spending 50+ dollars on a mouse was hard to grasp. The Mini did not disappoint. It's lighter than any mouse I've owned. I love that connectivity parts are all included. Keychron's mouse software is excellent.

The body is sturdy and doesn't creak. Buttons all sound and feel the same. Some reviewers don't like the Mini's hard plastic texture, but I prefer it – my Comfort mouse's rubber side grips are slowly decomposing, giving them a slimy feel. The only ding is the Mini's scroll wheel is average. We'll see how well its battery holds up.

Incredible value

This mouse is outstanding value: good switches (sound slightly different from left to right, not a major issue), the best sensor on the market, a great mouse shape for palm / fingertip grip... and physical buttons for essential functions! No need to use bloated software to change DPI or polling rate, it's all right there! Of course, finer adjustments require Keychron's software, but it is not necessary if you're comfortable with the default options. Worked on Linux right away, both with Bluetooth and with 2.4 Ghz wireless. The perfect mouse for a gaming computer + work laptop setup.

Do note that my hands are on the smaller side for a man, 6'+ people with giant hands might feel different about this product. Also, can't speak for the battery life yet, but the cable doesn't get in the way when used in a wired configuration, it all feels very lightweight.
