My hand does not sweat personally, and the application software works well. I got used to the mouse in 1 day. I liked the mouse, after the Avago sensors, taking the 3360 is like transferring to a Mercedes. It may seem that many reviewers "embellish" the sensors when they talk about "failures" and so on, but the difference can be seen even for simple work with a computer It is worth noting that I could not find a driver on the 2022 site, I had to download from a foreign one. The software has 3 profiles and 4 dpi settings (I still don’t understand how to add it, I can’t see it in any way), i. E. you set the desired dpi for these 4 and in general that's all . If you need more, you will have to switch profiles in the settings. Such to yourself. But on the other hand, the backlight settings are dark and for any color. For a price of up to 3 thousand, perhaps, an excellent mouse (I took it for 2300). If more than 3 . then rather, I would pay attention to the Corsair Saber
