from my side there 5 Star. Fast delivery as correspondence. The films are very well designed. A Quick Start Guide (it should be noted) is. With proper installation, they are barely visible. -no impairment on display -The back is now well protected What I regret is that I have not brought the set already in the first week. Price / performance => unbeatable Hinweiß: pays meticulous attention to cleanliness when fitting. Even the smallest contamination creates an air pocket under the film and does not look so great. I have cleaned the appliance with a damp cloth and rub dry with a lint-free absolutely handkerchief. Who "chamois", it should use. After cleaning the surface should not be touched, otherwise the fingerprints / impurities remain trapped under the film. Not quite pull off the transfer film (protective film of the protective film), but only the short distance with which to begin. The film is only slightly smaller compared to the area to be protected (rightly so). So start with the upper edge and let only 1 / 10mm space between edge protector and screen. Bring the slide slowly to the surface, so you can control the alignment and Verschnutzungen identify / eliminate early. For this purpose best to take a needle, with which you can push away the lint. Have the protective film now has a week after and no Ausfranzerscheinungen at the edges.
