The side buttons are covered (the two keys on the left side even separately), but it's just a small (not unpleasant) little more pressure to actuate necessary.
Laterally below the buttons the jacket is slightly dimpled what really attacking well and not so easy to "go smoothly" the mobile phone from your fingers can (can happen quite easily with completely smooth cases).
The back is made of two different materials: In the case with the S-shaped pattern of the right, rather narrow range is quite smooth, the left, larger area is rough and good grip (in the case with the X-shaped pattern is the X smooth grip and the rest).
All in all, I'm excited: The sleek design of the Samsung S5 is not spoiled by the shell, the feel of the original back wall I do not miss, because the cell phone really good attack with shell and really good in the hand. Only the EasyAcc logo I feel too intrusive - I would like to see more discreet. Nevertheless definitely strong buy recommendation!
