Fits very well to the iPhone 4S by the simplicity and the display is nice and soft. Magnet holds good, the phone fits perfectly in the Plastikumfassung and is effectively prevented by the plastic at the top of the fall out (other cases have adhesive films, be careful!).
Processing is fine for the price, the cover moves slightly to the left and right. The shell is supposed to protect and mainly it does. All switches are still easily accessible.
