Very thin hull and lègère.

This shell (original Samsung for GS6) is initially very thin and very light, I weighed, she 19g for a total weight of 159g with the phone, which is very acceptable, no l 'like having a weight in the pocket.
The shell is attached to the phone only the 4 corners, the rest of the phone is "naked" which does not spoil the look of this phone and shows the outline of aluminum.
Laccès buttons is not bothered and fast.
This shell is not type silicone gel or other, it is rigid. It surely will protect the phone from small falls but surely not the most significant drops.
