A:AnswerYes, it's normal for the mouse to click when booting your PC. The click you hear is the scroll wheel lock activating when the mouse receives power, so nothing to be concerned about! I had the same question before I realized what it is.
A:AnswerYes, I have massive hands and tend to do a hybrid palm/claw. It's the most comfortable shape for me.
It is directly comparable to the size of a Logitech G502.
A:AnswerTry switching it to a different port pr PC if there's any difference. You might also try blowing in some compressed air into the mouse opening and see if it helps to ensure no debris or dirt get stuck to it. If the issue persists, please reach out to our support so we can assist you further.
