Well, it's simple. To test this, I compared it to the iPhone 4S case that I have. Verdict: I'm a little disappointed, though this is not too bad. Why? The case "Amazon" has no plastic protection on some places unlike the one I own. These protections are located at the button "on / off" (top right) and volume buttons "+" and "-" on the left side of the iPhone. It sounds trivial but it very effectively protects from a fall those buttons. Basically, there is a plastic layer that hugs buttons so strengthens security in areas still strategic. At the beginning, I was offered a shell. It has fulfilled its role since when iPhone is dropped, it is the shell that broke, and not the phone. But hey, the hull was damn, I bought a case for ten euros if I remember correctly and it has fulfilled its role of protecting so far. In comparison, the case "Amazon" also seems too soft, flabby limit, silicon level compared to my current case that sounds perfect. The advantage is that at least we will not hassle to put it. For the rest, it's breaking even with my current case, it seems not a bad product, the grip is good because there are grooves on the back (after you like it or not, this is a matter of taste). Finally, I will finish by adding that the price is very correct.
