The price from Ali, this is the killer feature of this mouse that overlaps the minuses. For off. 2022 cost you can buy anything without the above drawbacks. The main disadvantage is that it does not save profiles. I'm used to that once I set up the mouse, I forget about this matter and delete the software / driver. Right there, unnecessary software will constantly hang in the tray. Well, completely useless dpi buttons. I understand one button to shove that would switch the profiles recorded in the mouse, and here there are two of them, and even extended (if you put your fingers freely, you touch the bottom one).
