The shell is not bulky, looks very good and fits perfectly. The build quality is great and all buttons / ports are within easy reach. Even the front is protected despite the deliberately understated design, if you put the unit eg times with the screen side down on the table. But the most important. The aluminum on the back unscratched.
Whether the housing so that a fall coped better, I'd rather not known :-)
Conclusion: good protection from scratches without compromising the beautiful design of the HTC One. I would buy the shell at any time.
