Like many competitive Counter-Strike players from the 1.6 era, I have a history with Logitech mice. And I still remember the exact time and place when I swore I stopped using them: it was in the middle of a tournament, during a crucial round. The mouse decided to fail on me, doing 360 degree spins in the air instead of shooting the one guy that would have won the match for my team.
I raged, then and there, and it's been almost a decade since I've used Logitech mice. Fortunately, I've returned to the fold at a good time: barring a couple of quirks, the Logitech G Pro Gaming Mouse is a fantastic, lightweight option for your fragging needs.
