I recently bought this M317 mouse. I never seen anything work this poorly. Lags, stops jumps, goes off in what ever direction it wants to. This is a piece of garbage. Yes all drivers and software is up to date and correct. Even Logi find device can't find it and that is while I'm trying to use it. Sorry to say this is the worst piece of equipment you guys have made. Can't even get the pointer to land on the next button.
