The product is high quality and fits perfectly to the iPhone 6 Plus. The rear is fitted with high-quality silicone similar to medical grade silicone. Slipping on smooth surfaces is thus hardly prevented. The side panels are made of high strength plastic, the cards are probably thus well protected against falling. I would have liked that the sides would have been equipped with extra soft silicone nubs. Thus, the already slightly wider iPhone 6 Plus a little wider but not non-slip for the hand.
