I have used this pad for years and it has stood the test of time. I have even washed it a few times with no physical or functional degradation. Works very well for both large and small mice. It has non-skid surface that keeps it in place. Works pretty well for corded ball style as well as modern optical and wireless mice. Highly recommended.
