I bought this shell there about 2 weeks to protect my HTC one I was afraid to break or scratch at the first shock. But I wanted to avoid spoiling her nice slim design with a too thick hull. Although this shell is not free (far from it) it has done its job. It does not alter the design and is mostly very fine. And a priori, unlike some low-end shells that deform over time, it seems sufficiently qualitative to endure in time!
