Very happy from regarding the appearance and practicality of this cover (except maybe the buzzer button that is difficult to achieve once in silence position). By cons very disappointed for the lifetime of the coating "carbon" it wears off quickly and especially on the corners (in spite of the fact to be very careful there). Well the cover remains functional but aesthetically, AC has nothing to do. Note also that the phone fell 2 times with this cover (from a height) and the phone has no damage.
