Review on XM1 RGB Gaming Mouse by ENDGAME GEAR - High-Precision PMW3389 Sensor, Vibrant RGB Mouse Lighting, Adjustable 50 to 16,000 CPI, Programmable Side Buttons, Durable 60M Click Switches, Lightweight 2.75 oz Design - Dark Reflex by Brian Garrett

What I like best about the XM1 is the (1) coverage and (2) M1 and M2 clicks: they're excellent and almost as crisp as the Logitech GPW (I've tried the best one before). The shape is great for the fingertip palm for me; However, the hump might be too low and too wide for some people, but that doesn't bother me. I alternate this and GPW for R6 Siege. A wireless version would be a real endgame.
