I picked up a Viper the other day,

The interface between the PC and mouse seems smooth and the buttons have a nice click to them. Otherwise, not too many good things about it.

It doesn't conform to the hand well. Compared to several other mice I have it is the least comfortable to use. The height of the mouse is a good 1/4" - 1/2" less compared to other mice, so in most cases the only thing on the mouse are your fingers and thumb. It also doesn't weigh a whole lot either given the size and lack of batteries. I would also like to see at least one thumb button on this thing. After all it is a gaming mouse and more buttons is mo betta. I haven't tried any of the high end Logictech mice, but I have a feeling that they would be a better choice for most people.
