The shell is very fragile, the battery heater, it requires 6 hours of charging and battery does not hold more than half a day if you use iPhone as normal (I mean it) BUT ESPECIALLY not at all compatible with the iPhone 4S !!!!!!!!! indeed the silent button on the top left is 0.5 cm lower in is covered in moitiée by poor shell. I spent 30 euros for nothing. I recommend that you have a 4 or 4s, really.
