It perfectly protects the phone, even if the protection tends to press the POWER button on my phone (because it is also protected by this shell). Also note, that when I want to take pictures with the flash, the thickness of the shell that the photo will be tainted by the flash reflection in the transparent shell.
The shell protects the phone. I recognize not particularly fear the fall. Nevertheless, it makes use less enjoyable because it thickens the device and makes it heavier.
This may be the "price" to pay to keep their phone a bit longer ...
