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

I upgraded from my MX Master 3 that was falling apart due to the poor material from the older model and it seems that Logitech learned the lessons. From a feel perspective is very much similar than the previous model but the construction feels more premium which is what you want considering the investment it represents. That said, it's worth every penny and I truly appreciate that you can customize the quick action button and adapt it to the different apps you're using. The significantly improved resolution is also a big plus from the previous model. Hopefully this one will last longer :)

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.

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 love the quality, performance, and comfort of this mouse. Obviously not being able to try something before buying can be scary, but I am glad that I went with my gut to buy this one. It was super easy set up!

Look, this is a good mouse. All of the MX Master series mice are good. On this edition they changed the material for the thumb rest and pinky rest area. I find this material to be more slippery than the old material used on the last mouse. This kinda defeats the purpose of having rubber in the first place. I've cleaned this rubber numerous times, and I keep waiting for it to sorta "break in" and be grippy, but it's not. It's slippery. I wish I could buy a different thumb rest cover, even hard plastic would be better than the rubber used on this mouse. This is me nitpicking though. The thumb press button is pretty cool when you pair it to a gesture. It's a quality mouse all around. It's a decent upgrade from the last version.

[This review was collected as part of a promotion.] Endlessly customizable, haptic options, full control of everything you work on and removing a lot of tediousness in all programs. The only issue is the low polling/report rate. The mouse is noticeably less smooth than it should be due to this.

This mouse has extra features a standard mouse does not. Unfortunately, some are locked behind the "online" version of Logi Options+ such as the action wheel. So if you work somewhere, you best check with your IT department to see if you're able to even use the mouse as company policy could disallow the app. With that being said, you can still customize a good chunk of the mouse using the "offline" version of Logi Options+. I'm still getting used to the SmartShift feel as it feels off to me. At first I thought it was a QC issue to be honest. The nice thing is you can turn it off if you don't like it which I may end up doing so. So 4* when considered the Logi Options+ nuances.

I preferred the feel and buttons of the 3. The 4 feels larger in the hand and while it is significantly more customizable, I just haven't found it was easy to work with for most things. Good product, if customization and options are important to you it is fantastic, but I'd recommend trying one before buying.

[This review was collected as part of a promotion.] I love how smooth and quiet the mouse is. Love the features of the Options+ app. My only complaint is the Right Click button clicks very easily, like too easily it happens accidentally quite often. The purchasing process online was a little strange, in that I have no purchasing history. It doesn't show that I ever order the mouse.

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.
