After searching on the net full of existing shells, my choice fell on Survivor who was then at a competitive prices, including postage, from Amazon. Perfectly deadlines, good packaging, the product arrived in perfect condition. The molded plastic shell hugs the phone and includes a glass that protects the touch screen of the iPhone. The whole is then wrapped by the "skin" like rubber than protection for TV remote control. The protection is optimal against scratches and other shots of everyday life. In addition, auxiliary output are charging socket and speakers protected from dust through their specific caches. All functions are easily accessible and the virtual keyboard is exploitable (some letters along keyboard difficult for those who have large fingers). As for me, it matches my expectations, there is nothing wrong!
