Really useful and cheap.

It's a bit silly, but I think I spent more time looking for a cover for my phone to choose a replacement model.
The choice of the Xperia Z3 was very quick: I use my phone for geocaching and inevitably, the rain was due to my Nexus 5 (oxidation preventing foreclosures letters A and Q in portrait mode). So I needed a waterproof phone and this is the only reason that pushed me to the Xperia Z3.

I'm not a big fan of covers flip-type cover is pretty, but in the end I prefer a shell and a shield: it is more expensive (2 items), but stronger and more functional for those a smartphone that comes out of the house and who will also hike.

This shell is not expensive but is really handy: it is not ugly for my use (this is a little fighter, not displease me) it has a center stand to watch videos from my table bedside, in short, very satisfied with this shell.

The phone has already fallen from my pocket fleece bitumen: no trace of impact.

Note that the square and besides the entire look of this shell is rigid: not believe that these are rubber cleats kind tire spikes, they are hard plastic squares.
