I have three tablet and therefore tested various films about the pose nothing to say it's the same as the other (no bubbles in a humid atmosphere (hint: hot shower when the bottom part is clouded ask the film)). As against the film at a granularity detestable, the affected is not pleasant and transparency therefore also leaves to be desired. On the other hand, I have boy hands, I'm not a mason (just computer), but my fingers scratch the film, albeit slightly, but at this rate the film will make 2 weeks (all other average movies last 3/6 months). In short even if the price is low there is better at this price! Too bad.
