Since there appeared to this product so far exclusively sponsored reviews are here now so my opinion: Ungesponsert. I actually laid 30 eating for the thing. And so I can only awarded 3 stars - because although the whole thing is very valuable to the touch and appears to be stable, the price is of course completely coated. Already half the required money would be short of the pain threshold. Otherwise: Stable, the S4 slides easily in, back appears scratch-resistant, does not carry too much on. Is narrower than the Commuter Series, which has my wife on her mini S4.
