Everything is in the title, very efficient hull to protect against shock S4, screenings, children, etc ... and very well finished, but ultimately difficult to use in everyday life as the phone becomes large, unwieldy and put in pockets, even coat. Furthermore the operation of different front sensors is altered, and the camera cover is very hard to open. I ultimately put my simple little silicone shell that protects a little less shock but is much more suited to everyday use.
