The changes between the Logitech MX Master 3S and the older MX Master 3 are pretty small, but they can also mean a world of difference based on your needs. And the support for 8000dpi also means that the mouse will work even on a glass surface without compromises.

In my line of work, I don't really notice the DPI difference between the MX Master 3 and the MX Master 3S, but this is definitely more important for those who do more graphic work or play games. With 8000dpi support, the Logitech MX Master 3S can cover more distance on a 4K or 5K monitor with less mouse travel. The MX Master 3 only had a maximum 4000dpi sensor resolution, whereas the MX Master 3S has support for up to 8000dpi. The higher the DPI number, the faster and more distance (sometimes called sensitivity) your cursor covers. Basically, it's the speed that the mouse can move on your screen. For those who are unaware, DPI stands for dots per inch, which is how you measure the physical distance when using a computer mouse. The other big difference lies with the DPI.

Despite this, clicking the two primary buttons is still very much tactile and not mushy, which is fantastic. While the MX Master 3 had pretty loud clicks (even though it was marketed as 'silent'), the Logitech MX Master 3S is incredibly quiet - you can barely hear your clicking, especially if you have something in the background like a fan or air conditioner. One of the biggest and most noticeable differences with this mouse over its predecessor is how quiet it clicks.

The Logitech MX Master 3S also comes in three colors, though all of them are pretty neutral and should complement any setup. All seven buttons can be programmed to your liking with the Logi Options+ software, which I'll get to in a bit. On the left side of the mouse is another scroll wheel for horizontal movement, two buttons for going forward/backward (default), and a clickable button where your thumb rests.
