PRODUCT WARRANTIES
We generally provide a warranty on parts and labor for one year after the sale and installation of each device. We also warrant our disposables products through their use or expiration. We estimate our potential warranty expense based on our historical warranty experience, and we periodically assess the adequacy of our warranty accrual and make adjustments as necessary.
