More relieved I was when those appointments a few weeks ago arrived with me. Based on my experience, I had specially ordered a set with multiple slides, justified by the concern that I would destroy only 1-7 films before I get a decent launched. The system with the two carrier foils on front and back, including easily understandable labeling the application, however, was simple - a small enclosed squeegee helped to remove the last bubble. DC sat the first film and sits even after weeks still without a single scratch or dirty edges.
The film is actually as promised absolutely invisible on the display. In addition, it is perfectly smooth, does not interfere with the operation and does not delay the touch function. Just a protective film should be. They served their purpose and affecting the users of smartphones not at all. 5 Stars
