Features include 8 responsive buttons (including a rapid fire button that sends a triple click), 5 levels of adjustable DPI settings and an uninterrupted 10 meter connection distance. With a 500hz polling rate and ergonomic grip that feels good in hand, the mouse is a no brainer at $7.50. How do I know it feels good in hand? I own two and use them on my gaming rig at home and on my Chromebook while out.
