Pros: i like the fact that you can adjust the weight and the dpi. very nice feeling mouse and it looks like it floats on my mouse pad with the lights

Cons: the mouse drivers that came with it disabled the scroll wheel for some reason, if i exit out of the software then i can use it again. it jumos across the screen everyonce and a while but its not to bad

Overall Review: im sure you could find a better one for the money

Pros: Pretty fast, stays cool enough

Cons: actually only adds up to bout 2.8 gigs.... why they call that 4 ill never know

Overall Review: they never give you as much memory as it says ie: 30 gig ipod = 27.8 gigs, 320 G hard drive = 297 gigs
