The glue was really difficult to remove, but from what I can see, everyone has a slightly different experience with this. It's possible that I have an updated version (if such a thing even exists, I bought mine in February 2022), or it's possible that my fingertips are so thin that I don't perspire as much and hence don't heat up the mouse. users of the g502 - I hope no one is insulted by this, but I can clearly state that she does not come to see me. Got pros: There is a place where the little finger can rest, making it comfortable to use (unlike the G502, which is shaped like an egg). It also has excellent software and cool lighting. These are some downsides: The wire connector is micro USB, and it is also pretty little - I did not have all of the cables, but fortunately the adapter for type-c went in, the legs are soft, and they scratch on everything.
