The mouse is really good. I couldn't remove the sensor. Excellent glide on all surfaces. In the minuses, I attributed the dull sound of clicks on the main buttons and software, which works quite unstable. The side buttons have an excellent click, the wheel also works fine. Regarding the size, then you need to look at the features of your palm. I have a long palm, but rather thin. Initially, it was very unusual to use a mouse with such dimensions, but after a couple of days I got used to it.
