The shell itself is - compared to other silicone cases - quite stable and slightly transparent, so that the back of the smartphone logo shows through. The envelope is processed accurately and high quality; All connections are easily accessible and also the two microphones and the infrared lamp are not covered by the sheath.
In addition, the grip of the smartphone is enhanced by the product, so that it slips from the hand difficult. At the same time the device is only slightly adversely affected by the silicone case that weighs only a few grams.
All in all, I would issue a strong buy recommendation, although the product in the long-term test still has to prove itself.
