A very good protection but ...

This shell is really solid, well finished and definitely provides excellent protection in case of fall (I have not taken the test so far).
But it has its faults including Batch, a weight that is felt well, also unable to switch applications from one screen to another by dragging the finger stopping on the net protection without reaching the edge edge of the screen and allowing slippage of the application; always due to inability to reach the ledge alphabetical selection offered by some applications to perform faster selection in searches.
Best of all, I could see a loss of reception between the use of the hull and the leather sold by Apple, in one place loss of reception of 4G with metal shell while I'm 4G boiled leather.
Conclusion: this is an excellent choice for this hull real protection of its iPhone, it deserves more than 3 stars can be largely assign 5. But it soon becomes a handicap in the use of the latter with manipulation which are no longer achievable and loss of reception, where my 3 stars awarded.
Note: I left after 2 weeks back on my leather shell.
