The MX Master 4 is an exceptional device. Better than ever. I loved my MXVertical. The MX Master 3X topped it. The Master 4 blew my mind and had me asking "how did they think of this?" A truly stellar, feature rich device. It's hard to imaging what Logitech will dream up next.

It’s good, there are some improvements from the master 3. BUT I prefer the 3 much much more.

Hearing that the MX Master 3 still feels like the better fit highlights an opportunity to make the MX Master 4 experience just right. Customizing key mappings and adjusting smart-shift sensitivity in the Options app often restores that familiar workflow feel, so please reach out directly for tailored optimization settings.
It was great until it wasn't. For two weeks, it worked normally, and if it continued like this, then I would have given it five stars. However, it started to randomly disconnect and reconnect throughout the day. Sometimes, it would take 15-20 mins before the mouse would reconnect with my PC. Also, when I move my mouse across the screen, it would randomly click and drag items. It has been getting worse over time and now I just don't use it. I contacted support and provided videos and information, but they still haven't sent me a resolution or a replacement, and it has been another two weeks.
No, I would not recommend this to a friend.

Mouse works well, I do get some lag now and again, but otherwise I would say no issues. It is comfortable in my hand as well. Love the side thumbwheel, but still working on muscle memory for all the buttons.

Thank you very much for your fantastic feedback on the MX Master 4. We're happy to hear you find it comfortable and enjoy the side thumbwheel. If you experience occasional lag, it might be caused by wireless interference or software settings, please try updating the software or using the mouse in a different location. Over time, the buttons should become more responsive with regular use.
Slightly narrower than my old MX Master 3. I have larger hands so I wish they made the MXM4 slightly wider. Also, Bluetooth is very sensitive to interference, so I have to use the external dongle. Otherwise very solid mouse.

Thanks so much for sharing your thoughts on the MX Master 4 – Graphite! We’re glad you find it a solid mouse overall. We hear you on the width compared to the MX Master 3, and we’ll make sure your feedback about larger hands gets to our product team. As for Bluetooth, the dongle is definitely the best way to keep things stable, but we’re always working on improving wireless performance. Appreciate you being part of the Logitech community and helping us make our products better!

Glad you’re enjoying the MX Master 4! We hear you on the software side. Some advanced features do rely on Logi Options, and your feedback on that dependency is noted. Thanks for sharing your thoughts with us.
If you want the best possible experience, this is the mouse to get. Smooth, sleek, connected. What more could you want?
