But:
The holes in the protective frame not sitting exactly in the center over the holes in the phone - which means that the original headset can not be used with the frame. A boring, as described by the predecessor is, strictly speaking, only with the silver-colored frame possible because the different colored frame "only" are painted and the hole again, the silver would come to light.
Also brought about by the staggered holes: the frame is sitting pretty tight and the bottom of the body to be screwed he does not go all together. The cut-out for the bump into the headphone jack of the mobile phone sits namely also displaced and generated at this point pressure on the battery cover. Here I was with a small round file ablating some material and then screw the frame without any problem or gap.
Another shortcoming is that the power switch can be achieved pretty bad with the / my thumb. Because I know better cases. At this point builds the frame - even if it is perhaps only 0.7mm thick - 1.5 mm for all the phone on. On the one hand because of the protective adhesive between the frame and mobile phone - in addition to the frame at the long ends also something but bulges (hardly visible).
