OP is right. This mouse does have issues. Many of them are related to the buggy cue software which I have battled for way too long. Biggest issue is if I have the dongle plugged in and reboot my computer it will hang. Once I unplug the dongle it boots fine. And of course the stuttering which is just horrible at times. I'm not into beta testing for paid products. The only thing wrong that isn't corsair's fault is the mouse it too big for me. I can't even reach the forward button with my thumb. I can barely reach the sniper button. This thing is going back to Amazon.
