Have I gained the protective sheath, since I own a iPhone5. The previous iPhone models were so much more stable, but the iPhone5 with its pure Aluhülle is a nightmare if it gets dropped again, because then there is not only scratches, but the Aluhülle has quickly ugly dents. So needed a protective sleeve, and the mix of polycarbonate (the black frame) and silicone (the green crumple zone) seemed only logical. And as is so often: As soon as you made provisions against shocks and, one no longer falls down the iPhone. Since I have the envelope, it's my time like three down. The third time just now, from my washing machine; pronounced drop height about 90 centimeters - result: polycarbonate frame breaks. I would say: when's phone had fallen from my balcony on the third floor, and the polycarbonate shell breaks ... okay, so you have to expect. But from the washing machine? It is to protect the purpose and raison d'être of the protective sheath against falls. If it's equal to the third time breaks - the moderate fall - which is a mediocre to poor performance.
