I upgraded from a Logitech G5 on my work machine. I still use a G5 at home for gaming, because the MX Master 2S isn't what I'd use for gaming (I need something lighter and smaller.)
But, I purchased it for my work machine. The goal was a more comfortable, precise mouse with extra functionality.
On the comfort level, I give this mouse 5 stars. My hand and wrist feel absolutely no strain using this mouse, it's easily the most comfortable mouse I've ever used.
On the precision and movement feel, I again give it 5 stars. It's nice and heavy, and the software let me set the acceleration just right so I can very quickly hit any location on the screens I use. I do use 3 screens, one of them 4K, and have zero trouble.
The extra functionality is where I have some issues:
The main buttons are wonderful. Nice click pressure, and large buttons for multiple grip styles.
The scroll wheel is again best of class; the SmartShift feature switching between Ratched and Freespin is absolutely genius, and I use it all the time.
The little extra button on top is also in a great position, very easy to use but not easy to hit accidentally.
However, the back/forward side buttons are a disappointment. I can use the back button after a month of training. I have to point outwards with my thumb so I only hit the back button and not the forward button at the same time. Then, to hit the forward button, I have to point my thumb inwards, which is a very cramped position to put the thumb into. I suffer RSI so this is an issue for me and I can't use that button much. As far as solving this, I would be happier with just having larger back button, and for those who need a forward button, they could use the thumb button for it. I realize that's a tough call to make, there's probably just as many people who are perfectly good with the button setup.
The horizontal scroll wheel is definitely good, thank you Logitech for including a sensitivity setting for that, it makes it very usable as a volume wheel.
The 'thumb button' is nice to have but to me it needs too much pressure to be activated. It's okay.
Overall, I don't feel there are enough issues to take a point off the product rating. They are very minor issues, considering the number of buttons, and an additional wheel that all had to be put within reach.
Battery life of this mouse is really amazing. I've been using it for weeks at work, never switch it off, and I still have 2 out of 3 power bars. Really, really impressive. It also seems that the battery is removable, at least for recycling; it'd be nice to know if in 3-5 years down the line, I can buy a replacement battery because the charge/discharge cycles will deteriorate the battery over time. But I might be worried about nothing, given that the battery discharges so slowly.
The software, so far, has been excellent. Very good remapping options, there's nothing I was looking for that I could not find in the selections. Custom key presses are allowed as well as pre-defined tasks. Per-application settings are great to have. The customization to all the buttons are complete.
Overall, for me the best mouse on the market.
