Logitech MX Master 4 Reviews

Happy with this Mouse

By Devin
Rated 5 out of 5
Date: 2026-05-28

I've been using this mouse for a week now and I am liking it a lot. I had the MX Master 3 and the main mouse clicking buttons stopped working. So I ordered this with the 4 year warranty plan (I'm expecting it to stop working at some point). I really like the thumb button and use it for Mission Control to see what apps/windows I have open and select a different one. The LogiOptions+ software is nice with all the settings and customization. I have read bad reviews but so far I am liking it.

I have been using this for 5 months and love it

Pros - The Logi software allows for unlimited customizations of buttons etc. - I have a button that allows for speeding up or slowing down the cursor speed which makes it easy to make very small masks in Lightroom and Photoshop - The second scroll wheel is great for using in Photoshop and Lightroom for different actions - The battery seems to last forever - Can be charged while using as usb port is on front of it unlike some of the Apple mice Cons - A bit heavy but this doesn't matter in the scheme of things - I don't find the left side large bottom button very useful, it's hard to get my thumb to press it and I will find I accidentally press it a lot. I usually leave it disabled - A bit expensive
