The envelope is divided into two parts, one has inside the silicone part and outside the plastic frame, which should keep the silicone on Iphone.
Unfortunately, as already described, the parts above and below the unconstrained phone from the frame, the thin silicon braces will probably not hold very long, because they do not fit snugly over the phone.
Some buttons are hidden and buttons on the rubber cover to use (on / off, volume +/-). This works well, but the cut of noise can be operated on / off not only fit and ultra hard since the slide switch up the rubber cover was left out, but this is quite thick. Clear negative at this point.
The phone is really hard through the shell, me is not so important, because I had the edge protection is most important.
However, the plastic frame fitted with me not so that he can become trapped telephone and rubber, but I had to cut all only clean so that the plastic frame is on the side on the silicon glue the molding seam of rubber. For the second Minus.
Last criticism goes to the charging cradle into which the phone still can engage, but disturbs the rear part, so that the phone can not load. Also not good!
A product with defects, a lower rating I have not made because of quite good value for money.
