No complaints about stickiness or dirtiness which is weird cause my wife uses my computer and I am totally OCPD yet can still live with someone else's greasy palms on my mouse. Seriously it just wipes down fine with a dry shirt or cloth, no problem.

The one complaint I have so far, which probably isn't an issue for most people is that I am just on my computer so damn much, and have been for like 16 years, is that I am having worse symptoms of carpal tunnel; it seems this mouse button and middle wheel click are a lot less "bouncy" than other mice I've used. I dunno if it's just the mouse or old age creeping up on me but my fingers are a lot more sore recently after extended gaming sessions than they used to be. The clicks seem to be less forgiving and less "spongy" compared to, say, my $5 mouse at work. That is the price you pay I guess for lightening fast response - no sponge to damper it. I still love the mouse though, fuck lifelong joint and nerve problems.
