And not only would I for-sure favorite the debut single from MX Master Mouse on Spotify, it's also a damned good input device for my PC. It's comfortable, fits beautifully in my hand, and has a lot of features that I love (especially the MagSpeed scrolling). I still accidentally click the thumb-triggered "Action ring" when I don't mean to, but turning the sensitivity down has helped with that. I need to spend some time setting the action ring up and getting used to it. I'm sure it's great but I just haven't used it much. Anyhoo, in summary, I've been using MX Master mouses since v2 and I love them. I wouldn't call an upgrade from v3 to v4 a necessity, but I bought one for home and one for work so I guess you could say they're my favorite. A++++++ 10/10 Would recommend.
The mouse is well built and works well but the "thumb button" and vibrating rest pad have been annoying.After trying to adjust to it for a few weeks, I turned it off but the pad still lightly vibrates when pressure applied. I had the MX Master 3 before and hoped this might be an improvement but that spring loaded pad and vibration have been very distracting. I do like that added features with the latest Logi Options software.
I switched to MX Master 4 from the 3s due to click button problem. Comparing to the 3s, 4 is heavier. The material is also more desirable for me as I don't really like rubber-stick-ness in my hand. Controling is much better with weight. I am in academic, so heavier the better control. Short key buttons are also convenient.
As a previous user of the MX Master 3S, I can confidently say that the MX Master 4 is on a whole different level. I am extremely satisfied with this purchase! Premium Innovation: The new haptic feedback system gives a fantastic tactile response that makes scrolling and navigating intuitive. Actions Ring: This new button feature is a game-changer, giving instant access to shortcuts directly at your cursor and saving massive amounts of time. Superior Build: The materials feel much more premium and solid in the hand compared to older generations. It is smooth, whisper-quiet, and provides the ultimate navigation experience. 100% recommended for any professional!
