I've had my G502 for around 3 years and it's served me well. Since then, however, I've been having issues with it. It's having trouble tracking on my corsair mouse pad, stuttering as it moves over black streaks (most likely damage imparted by too many all too close csgo matches). The slippery pads at the bottom are also starting to go, and it feels rough to move. I've always been interested in a lighter mouse, but loved the tracking on the G502. I play a lot of CS:GO, TF2, and PUBG. Any recommendations?
