The shell is really well made and fits perfectly.
By 2 "layers" makes the whole phone naturally somewhat thicker, but still is for me in the appropriate framework.
But one really has an optically nice envelope.
So far I have always normal TPU Silicone Case by example Mumbi used because they were simply cheaper in price and also have served their purpose.
Since the HTC One M9 but is already highly priced but I now also wanted something really good protection, it should even come to a fall.
