Although the back of the OnePlus One is really beautiful, I wanted to protect them, especially the edges of falling and resulting in damage. Since the silicone cases often dust collector (especially at the edges of the display), are only a hardcase came into question.
THE workmanship and materials are really super. No sharp edges or margins. Cutouts for camera, buttons, connectors, etc. are also made of high quality. By fluted structure the back is this very well in the hand. The grip is further supported by the slightly rubbery surface.
SEAT and the fit are also very good. There are no edges, form no gaps or the like. The OPO really budge in the case, yet relatively easy it is to part with it when you need it.
TO PROTECT yourself is to say that of course the complete back is protected. The lateral edges protrude minimally above the height of the display, so that the smartphone does not rest on this. Only the upper rims / edges of the housing (silver border around the display) are not protected, which is why they could suffer damage in an unfortunate collision. But this is the only point deduction, which I can do with this product. But I give it 5 stars, because due to the nature (Hard Case), another form is difficult to achieve. If you want complete protection, must resort to the silicone sleeve or a cover-case.
The ratio VALUE FOR MONEY for this product is really good. For my money I get a super processed case that looks quality and feels so.
From me a strong buy recommendation!
