** I LOVE the Razer Naga - left handed edition, BUT I've owned 2 of them, and they've both crapped out on me and started having major tracking issues that have rendered them unusable - Razer Naga Left Handed is what I have now. I RMA'ed it once back in 2014 for tracking issues, got a new one and it's been good since. Now it's starting again. Maybe I'll buy another one and hope that it doesn't happen a 3rd time?
