Logitech MX Master 3 Advanced Wireless Mouse Ultrafast Scrolling Ergonomic 4000 DPI Customization USB-C Bluetooth USB Apple Mac

So I've been using the MX Master line since the very first model, for about like ten or fifteen years now. I have always loved these mice. They fit my hand absolutely perfectly. The control wonderfully. The battery is excellent. The side scroll wheel is extremely handy to have. They have a decent enough amount of extra butoons (M1 left, M2 right, M3 scroll click, M4 forward, M5 back, M6 thumb, M7 scroll mode change button) These are IMO the single best line of mice you can purchase for general everyday sort of use. They work as good for office work as for gaming or for internet browsing. That said, there is always something that is screwed up. Each model has something that prevents this from being the best mouse of all time. So I'm mainly going to compare this against the MX Master 2. They kept the soft velvety rubber palm rest pad that I absolutely love. The texture is slightly different, but it is still extremely comfortable. They removed the rubber coating from the scrolls wheels, that kind of bothers me. But the side scroll wheel is much more accessible than the previous model. It is larger and positioned better. The side buttons (back/forward) have been significantly improved. They are (BOTH) actually usable now. But still, you got a ways to go Logitech. Just make them bigger and move them forward more, how hard could it be? Unfortunately, the improved side buttons seem to have come at the cost of a diminished thumb rest button. On the previous model, you could press down almost anywhere on the thumb rest and the button would activate. With this model, only about a quarter of the area will work. And you can actually feel it through the rubber coating, where you can press. It still works mostly good, but their are times that I don't hit it initially. And it does take slightly more effort to press it down. I noted this on my review for the MX keyboard as well, but the software is not nearly as good as the previous generation (they both utilize the same software). There seems to be comparatively little customization options available. Instead of being able to create your own command for any given input, they now only have preset options. Luckily this is something that could be addressed and improved upon at a later date. If you read this Logitech, please improve the software. One nice thing is if you have the MX keyboard as well, you can remove one of the USB dongles so that both keyboard and mouse function through the same one. Read more

This mouse is an awesome piece of craftsmanship. Not only having app switching but also switching between devices in a seamless way was a genius addition to the product. All around I think this is a great professional mouse and Logitech has outdone themselves with intuitive features for workflow. As far as gaming I would say it is not exactly top rate for competitive, but completely viable. Especially for more precision oriented applications such as shooters as any key can be reassigned and DPI switching between 2 DPI profiles is an option. As a digital artist the side scroll wheel is perfect for resizing asset or used for side scrolling and strafing in my 3d art programs when working with landscapes, etc. The sensitivity is on point while motion is still swift and smooth for UHD resolution. As a gamer I like the mouse though I am not competitive and may not be as responsive as desired by the competitive circuit, but I have taken preference to my MX Master 3 Advanced for shooting titles for the precision this mouse features. The magspeed scrolling is a QoL feature I had no clue I wanted but will probably not give up in future purchases. Also have surface tested the mouse between 3 different styles of mouse pad, wood, glass, and metal. The Dark Field sensor seems to function exactly as advertised. Any surface including glass. Personally prefer mouse pad just for the sake of maintaining conditions of the skid pads on the mouse. As far as cons for this mouse the size could be a pro or con. I have larger than average hands and this is one of the few mice I've used that I find completely comfortable, my previous favorite was the Microsoft Sidewinder a decade ago. I do have some concern for it being a good mouse for people with smaller hands. Read more

My mouse with AAA batteries lasted longer than this mouse. I'm not entirely sure why this mouse isn't nearly long-lasting. My Microsoft Sculpt mouse lasted about 2x or 3x longer than this mouse. I probably have to recharge this every two weeks. The Microsoft Sculpt mouse I literally forget when I last replaced the batteries. Nonetheless, the Logitech mouse is very functional. It feels strong and durable like an iPhone experience. There's not much I can provide in justification about this mouse and its functionality but there probably is. Remember the first time you learned to use the mouse on your computer? There was this learning curve to it that needed time to adjust until you were accurate with it. This mouse's roller is bringing a new skill into the mix. The roller is very slippery but almost the exact optimal resistance to add a new option in your scrolling experience: Ex. Standard mouse lets you scroll in these variable spins: - 1-2 pages at a time by spinning slowly and feeling the bumps at each roll - about 5 pages at a time by spinning a bit faster and feeling about 3-4 bumps at each roll - spinning as fast as you can to get the page as far to the end. - if the page is really long, skip that and use the virtual scroll bar The Logitech mouse is the same as the standard mouse but remember I said it's slippery. - 1-2 pages at a time by spinning slowly and feeling the bumps at each roll but the bumps are a lot closer (e.g. like a gear's teeth, there are more teeth and closer together). So there is more definition. - about 5 pages at a time by spinning a bit faster and feeling about 3-4 bumps at each roll (slippery part since there are "more teeth"). - spinning as fast as you can get you the fidget spinner experience. Sometimes you don't want it to spin forever and think a regular mouse will stop right away. Not so with this mouse. If you spin this, expect it to spin like a fidget spinner until you manually stop it. - This fidget spinner effect lets you measure your roller spinning strength to help you develop skills with your accuracy. I'm learning to scroll in long pages without the need to use the scroll bar. In essence, the major change is in the scrolling. You'll need to relearn a new skill, but the skill will not be as hard as when you first had to learn how to use the mouse. Read more
