The first impression was very good. Three films, a tool to remove the bubbles, an adhesive tape to remove the dust and a microfiber cloth. So far so good.
However, it has managed none of the films on my SmartWatch. The first has not simply held and in the other two it was not even possible to remove the film struktorierte on the actual protector.
So far I never had any problems to install protectors on my smartphone for example.
So this product is a big disappointment and not recommended.
