I'd give it 3.5/5 stars. Pro: Has customisable settings incl sensitivity and LED Nice fit, conforms to hand, light but not too light. I have medium sized hands. Cons: Average quality of main buttons. Left, right and middle mouse buttons feel (and sound) slightly plastic, like that cheap plastic button sound which can be irritating once you start to notice it (its the mechanical sound of the physical buttons when pushed, not the mouse click sound itself). IMO not worth RRP, only worth when on special. My previous mouse was Logitech G402, despite the specs, Prime Mini is not much of an upgrade.
