Roccat Sota, no if you're a sweaty user. Roccat Kone[+], so far so good although the texture of the logo coming due my sweat. The rubberised texture has no problem with my sweat. Roccat Kave, yes very good

Uh, the material at the logo is different with the material on the body. Different rubber/plastic I guess. It started to have bubbles, out of annoyance, I scratched them off

Not sure with other mouse but this happens on Razer Ironclad as well.

Can't say much for the Pyra Wireless. It's not the friendliest wireless mouse to use. But once you get past th syncing hassles, it's actually quite good.

All sota having this problem.. i got 3 customer have they Sota out of form d.. 

Sota is the mousepad.. not the mouse.. the mousepad like benjol like tat.. haha.. a small hump..
