I have chosen for this cover, because here I had already ordered a for my One M7. I was always looking for a prop envelope that is not too tight and you have to rid his cell phone with all the violence of it. Therefore, I have decided then for plastic bags, however, most of Platikhüllen formally with all their might clings from a plastic in your pocket and it makes an impossible, his cell phone only times rauszuholen briefly to look at the clock. Not so with this envelope. It is easy to deduct from the phone and also so easy to fix precisely again. The material of the shell is simply a hit. The casing soft so you have to make any governmental act of it to pick up his cell phone from his pocket. Nevertheless, the shell is rigid and stable. I can pronounce an absolute buy recommendation for this cover for all who want a plastic bag which is stable and is easy to pick out of my pocket and just as slippery. I am completely satisfied with the shell and can absolutely recommend it. Greeting Marcel
