I have a Kensington Expert Mouse which, despite the name, is actually a trackball. I've had it a long time - maybe 5 years - and the edge of the wrist rest became hard and sharp. I actually cut my thumb on it. So I emailed Kensington about purchasing a replacement wrist rest. They sent me one for free.
I am duly grateful.
The replacement appears to be a different material - leastwise the surface is different.
