I already had a stand shell (muvit) on my previous smartphone (Sony Xperia Z) and I found here very useful. So I wanted to find the same thing for my Sony Xperia Z1. The accessory comes closest muvit is not a shell but something that sticks to the back of the smartphone: not trust. I found the shell Covert on Amazon and I bought it. I'm very happy! It is easy to install: the smartphone snaps into the shell of the case. It is rugged, stylish (it looks like leather) and especially, she is not afraid of water, which is pretty good for an accessory that is expected to accompany a daily water resistant smartphone! I recommend!
