Since I use a wooden box that is working extremely accurate (iWood6) and only Minimals was higher than the display, this film is like the small depression now made perfect and the iPhone feels again around - just protected.
For the attachment you have to take your time so that the result is perfect. I'm very fussy and tolerate under the film not a single dot. The best a room with no air movement (Close) so that the dust from the air is not very spread around. Subsequent clean the phone thoroughly with the enclosed cleaning cloth. Thereafter, the film removed from the glass and place it as soon as possible to fit on the phone. I have first "dry" laid it to me to remember the best position. After touching briefly and watch as it firmly attaches itself. If all was well cleaned, the glass is pressed briefly with the cloth firmly and it should be perfect. I have - despite accurate preparation - three test used. If an air bubble remain, it is often sufficient, the glass at the nearest corner gently lift with a fingernail and to delete the affected part again evacuated. If, contrary to expectations, a dust particle has remained under the glass, pulling the glass on top again and removes the dust particle with the enclosed blue tape (do not use cloth and never touch the bottom of the glass with your fingers - it just makes it much worse). If the blue tape to be already contaminated, you can also use scotch tape to remove dust. Anyway - after the third attempt it was with me 100% perfect. One does not see the guard, only the Home Button is now a little deeper. The processing of the film is very good, fit well. I'm going to order one and install it on the phone to my wife.
Thank you for reading!
