I work in construction and handle a lot of heavy, abrasive material everyday 6 days a week and with a metal case cover for my watch and this screen protector its saved my watch already a dozen and more times from being broken and destroyed, i will buy this product again in the future and use it again if it somehow is broken from this point on.
