XtremeComputing has posted a review on the Raptor Gaming M1 mouse and P1 mouse mat

As for the resolution tests the raptor performs well at 1024-768 and also 1280-1024 at 1600-1200 there was a notable speed decrease ad I had to again adjust the mouse settings in the game options, this I would say is outstanding, considering that this mouse retails for under 20 pounds I think you would be hard pressed to find another mouse which offers you 1600dpi response timings with the quality of the materials and construction
