I bought this and the MXS keyboard together. 100% worth it. I use the programmable keys to do Excel functions I normally do by hand. It's safe so much time. And the mouse feels so comfortable. The thumb button is a little weird at first. But it's worth it
Smoother scrolling, and I love the clear covering on the left and right click. What an update of improvements! I want 2 more! I have 5 prior versions of the MX Master, this is the BEST MX to Date!
Mouse is awesome to use. Only complaint is sometimes my button mappings / customizations are dropped and then I cannot get into the logi options app to reset my mappings. Not an issue with the mouse itself
Long time user of the mx master since the first its overall a great mouse but the gesture button is infuriating my thumb clicks it all the time wish there was a way to turn it off in software
Still a fan of MX Master, but disappointed with this one.

I was looking forward to the 4, I've used the MX master since the first one and usually recommend them to all. Not this one though. Moving the gesture button to the side was a big L. MX Master 3s is still the best one. This one slips from my grip far too often. Don't buy it, get the 3 instead.
