I have one of these too and only issue is an aggressive grab at the mouse I could hit keys I did not intend. To be clear, this mouse is a mouse but it is also a keyboard. It works like having two keyboards connected to the same system. My hand size, like others have mentioned, had me hitting keys when I didn't intend too. I would expect it could have adjusted to it for the performance others are getting out of it, but couldn't get passed the occasional inadvertent key presses. Can only recommend trying to see how it works for you, it is a high quality mouse and keyboard combo. The in game add-on is helpful but does add another add on in game to deal with.
