My review below:
++ The shell has a very good fit. The phone sits absolutely firmly in the sheath. Nothing is loose and all ports are accessible.
+ The lateral switch of the phone are still usable, since the side circumferential rubber at the level of the buttons is slightly thinner. The effort required is somewhat higher.
- It is very thick and makes the already great device very clunky. The otherwise elegant slim S3 is thus to HTC EVO 3D and continues to lose pants ash suitability.
- The material does a substandard impression. The rubber shines somehow quite cheap and what bothers me even more, the frosted glass back of the envelope is very slippery. While the original is back plate of the S3 very slippery in the mobile phone, the device must be definitely supported laterally to the shell to maximize usability suffers.
Overall, I will not use this envelope further.
I ordered another envelope of iProtect and wait for the delivery.
