The HTC One is very well maintained in this case official (fortunately the way). There is indeed a little game when touched corners of the hull but it was precisely intended to be removed and installed easily, while maintaining sufficient the phone to do so not alone. Not easy to explain, but if I had to use an image, I would say it is like a car seat belt: it is easily pulls slowly going there but it freezes on impact. Functional bonus: * You can call having the folded flap (this avoids having the ear heater), it works very well for me. * You can put the phone in landscape mode for watching videos, taking pictures or videos timer. Finally aesthetics, nothing to say: it is very class. To summarize: super happy with my purchase after 1 month and a half of use.
