    • If you’re looking for an amazing mouse at an affordable price…
Style: With Palm Cushion Color: Graphite
Very ergonomic, user friendly, responsive, and versatile are just some of the words to describe this product. As someone who has mostly used Apple products over the years, this mouse is just as good if not better.

    • Super comfortable for large hands, silent clicks
Style: With Palm Cushion Color: Off White
I’ve been using the Logitech M850 L for work and daily use. It fits large hands really well and feels super comfortable for long hours. The thumb rest, quiet clicks, and smooth scroll make a big difference. Easy Bluetooth setup and the battery lasts a long time. Highly recommend if you want comfort + silence. ... show more

    • Best mouse I ever bought
Style: With Palm Cushion Color: Off White
I had this mouse for years and years until it finally just cut worn out. So I decided to buy the same model, but they had a larger one which their TECH SUPPORT said would be better. I found that not to be true. The smaller one really fits in your hand like it’s not even there so that would be my suggestion, but a great product overall. ... show more

    • Silent click?
Style: With Palm Cushion Color: Off White
The mouse is good but what happened to silent clicking? Logitech has the best silent click technology of any mouse ive tried on the M650 model but with both this M850 and the MX Master 4, the clicks are significantly louder. Not on the level of a normal mouse but when im shopping for silent click, i expect silent click. Also the cushion seems kinda pointless. If logitech would make a mouse with the MX Master ergonomics and M650 click silence, that would be pretty sick. In the meantime, im going back to M650. ... show more

    • Good mouse, but not for gaming
Style: With Palm Cushion Color: Graphite
Obviously this mouse is not made for gaming, but its hard to find a silent mouse with re-programable side buttons, which is why this mouse is decent. If you are silly like me and bought this for gaming, you can buy a "LOGITECH Bolt USB-A" to not use Bluetooth, which will make a NOTICEABLE difference. If you're a member of the giant race, consider saving 10 dollars and buying the M840 L version without the cushion, as my palm does not touch it (The mouse is still a good size despite this!). Overall, its a large, silent mouse with 3 extra re-programmable buttons and software (Logi Options+) to customize it. 4.5/5 ... show more

    • Great mouse!
Style: With Palm Cushion Color: Off White
This mouse is replacing the Logitech Master version. I wanted a Bluetooth mouse instead of using the Logi dongle. I liked the larger size of the Master and was worried this one would be too small, resulting in cramping. So far the M850’s size has not caused any issues. It is also very lightweight, which reduces fatigue. I also like being able to move the mouse between my two Macs without moving a dongle. The mouse easily switches between both and the buttons work as expected. The only thing I miss from the Master is using the middle button to turn on/off continuous scrolling. ... show more
