The phone is well protected. I used during 2 years the same product on a Galaxy S + who fell several times on tiles from a height of 1 m without damage (the phone bounces!). Here the shell is a little thin, so to see the use ... I have not tested voluntarily.
Overall, the shell adapts very well on the phone and protects any good coaching that will nickel if one day you want to sell your phone. However, one point less because the top and bottom of the hull differs a little. It's just a cosmetic problem. And the hole for the microphone is off, the microphone arrives right on. This may be a problem on my copy. I did not return because obviously it does not bother correspondents.
Screen Film: it is fairly rigid. During the installation on the screen after cleaning with a microfiber cloth and the small cloth provided some bubble diameter 0.5 to 1cm remained. I could easily drive out to the outside by pressing with your finger. Result plus a bubble! Then, no peeling. In the end, this film is almost invisible !!! Under the fingers, it is a little less sweet than the original screen, but we made it very quickly.
Finally, a kit price / quality excellent, which I highly recommend.
