Logitech MX Master 4, Ergonomic Wireless Mouse with Advanced Performance Haptic Feedback, Ultra-Fast Scrolling, Black

This mouse has a super comfortable ergonomic design and grip, glides smoothly on the pad, has many configurable options via Logi Options, supports gestures, and offers haptic feedback on the show action ring. My wrist/hand/fingers never get tired after 8+ hours of use. This mouse represents next generation enhancements to the MX series. If you like a very configurable, very comfortable fit, and typical high quality Logitech product, then this mouse is for you.

I own a couple of MX Master 3 mice and recently replaced one of them with an MX Master 4. The MX Master 3 & 4 mice are the best mice I have ever used. I highly recommend them. The ability to spin the weighted scroll wheel at high speed to quickly scroll up or down a document or web page, or to quickly zoom in and out, is very useful. The MX Master 4 is a great mouse, though the improvements from 3 to 4 seem very minor. I actually prefer the lower thumb-button design and thumb scroll-wheel design on the MX Master 3 over that of the MX Master 4, but they still work great on the 4. I was disappointed to discover that, for my use cases, the new haptics feature doesn't provide value. I do like the addition of the third upper thumb button. I would happily buy either the MX Master 3 or MX Master 4 again.
