Been using my everglide giganta for 2 years. I let my friend try it on his boomslang razor and it made him order one and toss his 3M.
But when we went to a computer convention Nvidia had a promotional green mouse pad in the shape of a circle. He likes it better than the everglide. I think 3M makes it but I don't know for sure.
I got one too but gave it away. The teflon on my intellimouse is worn out but the mouse still works great on my everglide.
