Shockproof, but very brawny

The material make a very valued and stable impression. But the shell is quite thick and the iPhone 5S now acts very brawny. I think, however, that this can not be avoided if you want to have a reasonable fall-protection. The unit is very well located in the casing and can be found very easily and put in again. What I did not like so much, is the plastic cover on the back: This solves unfortunately very easily from the shell actually (partly even when the device out of his pocket pulls). Now I have a bit hurried along with superglue and now everything is fine. Would the said rear cover is not so easy to solve, I would look at the price-performance ratio as well. So I find it average.
