The mouse got me a year ago. Before that, I used an old optical mouse for 100. In the hand lies perfectly (although I had to get used to the first 1-2 weeks). Add. I don't use software. In it, you can customize all the mouse buttons for yourself or select the "CHIT mode", which will cost you a round sum. According to the manufacturers, it helps with shooting. At the beginning there is a demo version for 1000 shots. As for me, it's a waste of money and an unnecessary function. You can adjust any sensitivity for yourself and switch it. There are a lot of settings with macros and other garbage. Did not bother. Convenient switching between click and sensitivity modes. The cable is wrapped in fabric. (A part of me has been erased and now the cable itself is visible, sadly). I do not use a rug, the mouse rolls perfectly on the table. On the side there are ribs that do not allow the hand to slip. But very often dust clogs in them. The icon itself blinks. Outcome: Satisfied!
