Query: Washable Computer Mouse

This mouse was totally unacceptable. I purchased it for use at work becuase there are multiple users on the computer I use. It was difficult to move about with or without mouse pad. None of the users liked this and we went back to the old style. The difficulty were the soft plastic nubs on the bottom. Have no idea why they were incorporated into this mouse. Others don't have these.
