I've gotten stuck several dozen films in various devices of mobile phone, digital camera over to tablet. Meanwhile succeed virtually invisible and completely free of bubbles through the exercise. At an invisible stick but here is not to think. The films are simply too small. PDF files can be neither borderless still invisible glue. Even a straight stick with the same everywhere wide margin is difficult to achieve. This ideal brings the G Watch by their simple form and clearly visible edge with actually. Especially with a clock a film should be invisible but, finally, a clock is always visible.
The films themselves are qualitatively usual good, but not recommended by the poor fit.
