First, I must say I can only rate the rear, on the screen, I have a slide of Apple and am very satisfied so far. But now the InvisibleSCHIELD the material the manufacturer promise not too much, the film can hardly be what harm. So an air bubble from sticking just with the needle to pierce hardly goes. And since we have been coming for the first problem, who is not fine motor stage talented and can take 30-60 minutes, can be equal to it alone. Applied the film is quite fast too, it can be quite easy to get in the perfect position thanks to the provided release spray yet. But until you get down the little "wings" at the corners some time passes. It is also useful to look at the video from the manufacturer. Although It's that easy but not you get little tips.
Drying should be one they already have one day it is indeed after 12hours already quite firm but when the corners stand for a day is not helping. Smaller bubbles and imperfections disappear as promised after a few days.
For me, the film is now for 2 months and it still look like on the first day only a thin strip at the corner I had to cut off now (box cutter) then simply press the rest back on and finished.
In the car, I have a Brodit mount the after slightly bent to fit well with foil. Brodit passive holder / Holder with Tilt Swivel for Apple iPhone 3G completely flocked for soft slide! No scratching! iPhone 3 G
