Given the previous comments for this product, given the price of all + glass screen of the iPhone 5 (and several glass screen) and given the low price of protection, I decided to try the step. Namely, the seller provides both protection for the screen and two protections for the back. My opinion is based only on screen protector (the back of my iPhone is protected by a cover).
I am amazed by the quality of protection: it is invisible in normal use, very very discreet if you look closely the cuts (for the front: cutout for the earpiece, front camera and proximity sensor up, cutting down button).
The cuts are very well adjusted with the exception of one: that of the proximity sensor (left earpiece) is a bit on the right, cutting is not perfectly centered on the sensor, but this shift does not interfere in any way the operation of this sensor, whose aim is to turn off the screen when wearing the phone to your ear).
Otherwise, all other cuts are perfectly adjusted (the front camera is not hindered by cutting, cutting the hair cell button falls around the button without any lag). The edges of the fall protection perfectly well and come kiss without overlapping the edges of my bag (a Speck CandyShell for iPhone 5).
Protection necessarily mean thickness when passing sensitive finger on the Home button, but it stays contained. One feels, once installed, no discomfort and no difference in the tactile quality, and the most subtle movements are perfectly captured by the phone despite the protection.
The installation did not ask me any particular problem, although my first try has attracted some dust (fortunately two of each protections - front and rear - are provided). There is only one protective film to be removed, unlike another brand whose many movies to withdraw have resulted in the tearing of protection.
For installation, it is advisable to work on a damp surface (cleaned with a damp cloth to "glue" the dust), but not on a plastic tablecloth (too static). Sure surfaces (screen or back) must be perfectly clean and dust free (possibly opt for a dry gas bomb).
Start at the top to align the cut of the earpiece and the front camera, by removing the protective film As the sizing. If the top is aligned, cutting the Home button should fall perfectly around the button.
During installation, air bubbles were formed: they are easily hunted with the finger or the supplied map. An air bubble was caused by a tiny dust (almost inevitable even being careful). Rubbing gently with the card, I was able to eliminate it, making this little invisible accident.
A very very good product so that I can not recommend that even the most manic seeking their screen without breaking the aesthetics of their iPhone!
