Cheapest in UK ? Outside UK people pay 40$ for this one. Sensor is new actually, optical 3330 PMW, hard to fault, or you have to swipe mouse like a robot to make cursor spazz out, did research looks like it's similar to logitech's 502 403 303 g900, nixeus revel's, ss rival 700, some top mad catz mice sensors, just lower max speed, and less dpi 7200, so should be cheap nice gadget for fps gaming! Postage 1.98 GBP via collect+ option!https://www.youtube.com/watch?v=rjn9Bdc4-iQ
small review! Cable might be not for everyone taste.. but fixable with bungee or maybe some table clips!
