Well, got mine in and messed around with it for about 30 or odd so minutes.
So far, I do like that I'm able to make faster and more consistent flicks with rather good control, although the surface hasn't 100% sold me in comparison to the traditional cloth pad. Just feels weird, but it may take some time for me to adjust. I know for a fact I can lower my in game sensitivity just a hair.
Borrowed my old G500 that I sold to a friend and it seems that the hard version and possibly soft work with the Avago ADNS-9500. The only problem I saw was the slight pos acceleration inherit to the sensor. Retested the Qck and Talent and lost perfect control well before 2m/s (neg accel)
Edit: I forgot to add that the Deathadder has a ridiculously high LoD of 5-6mm on this surface without the tape fix.
I'll either do a full review, or continue adding to this thread.
Skylit - the slight pos acceleration inherit to the Avago 9500, i still haven't been able to read anywhere if this accel is consistant or is it random??
