I'm currently using the Redragon Storm Pro, it served me well for two and a half years, but after daily use the battery is slowly dying, the feet are worn out and I can't find a replacement for them. The software doesn't like high resolution screens and won't work properly unless I drop the screen resolution to 1080p.
Games I play: Guild Wars 2 (MMO) and various first-person shooters here and there, nothing competitive
Right-handed/symmetrical
19x10cm
Wireless, never going back to a wired mouse
My mouse grip is somewhere between palm and claw (Relaxed claw?)
Lots of buttons
Don't care much about weight
1200DPI is my current setting
Budget: $100
No Logitech please, never again.
