#0: The pad is very smooth looking and might be worth a try :i - that is, if the curser doesn't skip or jump when using an optical mouse.
That said, I think the pad is too small and it also seems to be a bit too high. Shape wise I'd like something closer to the shape of the Steelpad 4S.
Btw: What keeps the pad in place on the table, when you're using it?
And could you please elaborate on what you mean by writing that the pad "solves the problem of high-friction pads"?
