Logitech MX Master 4, Ergonomic Wireless Mouse with Advanced Performance Haptic Feedback, Ultra-Fast Scrolling, USB-C Charging, Bluetooth, Windows, MacOS – Graphite

Best Mouse I have EVER USED
I use this mouse (and every other mouse for that matter) for work and I am so happy to say that this is certainly THE BEST mouse I have ever used.Where do I even start: the way the ergonomics work to give you the best experience to design aesthetics to the good battery life to the USB-C charging capability to the absolute pin-point precision and accuracy of cursor movements when used on a glass-pad (I use an ASUS ROG glass pad) to the thumb-rest to the amazing experience enhancing haptic feedback … and the list goes on as you can see.I read a lot of reviews online and saw probably close to 15-20 video reviews on YouTube and based on my experience of 3-4 days of using this mouse I can tell you this: This is probably the most amazing mouse I have ever used. I have been using Logitech MX Master series mice since 2015 and currently have 2 more MX master 3S mice that I have been using for years and I can tell you this is the best one yet. Everything the YouTube reviewers said about the top curve to be too much or the haptic feedback not good enough or the side wheel to not work as amazing as it sounded in theory – all of it was absolutely and totally WRONG! I loved everything about this mouse from the get go. I couldn’t find any fault with any of its features or capabilities. I LOVE IT!!!!!The mouse comes with a USB-C receiver which I think is awesome. There is one drawback in my opinion however, and that is that at the price point this mouse is selling for, it does not come with a charging cable or a charger and I thought that was a huge let down by Logitech, a very stingy and cheap move on Logitech’s part to not include a usb-c charger with cable while asking for a price they are asking for in November 2025. Otherwise I love the mouse for what it does.If you are on the fence to make a decision, I highly recommend it. You will not regret it.

Some OK ergonomic changes, lack of dongle adapter
[Having spent a few more days with the mouse I’ve upped my review a star. Some of the ergonomic changes I originally disliked I’ve grown used to, and I do generally find the overall feel of the mouse, including the slightly softer click impressions, rather nice. My biggest complaint is still that no USB/USB-C adapter was included, and also some ongoing fussiness I still experience with LogiOptionsPlus on one of my two systems.]The mouse itself is good (great if I didn’t have the 3s to compare it to). Pushing back the two forward/back thumb buttons to make room for the switch formerly on the thumb pad is a mistake – it makes one flex the thumb backwards to reach “back”, while the relocated thumb pad switch is paced too far forward. Overall this arrangement is significantly less ergonomic. (I couldn’t care less about the haptic feedback which this was all supposedly done to facilitate).The would make me rate this model 4 stars vs. 5 stars for the 3s, but the most irritating sin here is switching to a USB Type C dongle, without including a USB-to-USBC adapter. My desktop is six months old and fairly high end, and the only USB-C ports are on the front of the case, and apparently don’t provide enough power to run the dongle. So I – and I expect a huge number of this thing’s purchasers – have to separately order a 3rd party converter. Those aren’t expensive, but the mouse is, and if you were expecting to use it on arrival and don’t have a converter lying around you’ll have to wait an extra day or two, or order one at the same time. For the extremely high price I don’t think inclusion of a cheap bit of hardware that’s obviously necessary for most users is a lot to ask.It’s worth noting, I suppose, that LogiOptions+ remains a massively bloated utility, which also has years-running issues with unresolved, as-yet inexplicable “backend connection issues” with some (not all) Win 11 systems.

Chegou em perfeito estado, produto excelente. Meu arrependimento é de não ter comprado antes. Porque pra produtividade no dia a dia é excepcional.

J’ai remplacé ma Magic Mouse et mon Magic Trackpad par ce produit au design et aux fonctionnalités remarquables. Je ne pensais jamais pouvoir me séparer de mes anciens outils, qui m’ont été d’une grande utilité lors de nombreux projets. Je ne regrette cependant en rien mon passage à la souris Logi. La prise en main est excellente et ne laisse aucune trace. Son design évoque le Liquid-Glass et ses boutons sont beaucoup plus pratiques qu’il n’y paraît. Cependant, je m’attendais à un retour haptique plus prononcé dans les applications. Cela dit, il s’agit d’un produit unique et remarquable.
