I have now for about 2 months, the shell of Ringke mentioned herein and may only report positive. The processing of the envelope perfectly matches the Galaxy S5.
On the bottom there is room recesses for covering the micro-USB port and the microphone. On the left side 1 opening for the volume button on the top 3 Aussparrungen for the speaker connection, the second microphone (?) And the infrared transmitter. On the right side 1 opening for the on / off button and on the back 2 cutouts for the camera and the loudspeaker.
The shell is a perfect fit. This is on the one hand quite positive because allle notches match the keys and everything is in its place. On the other hand, the casing can, however, relatively difficult to remove.
The back of the case is inspired by the original collection of small dots leather design of the Galaxy S5 and makes a high quality impression. The cutout for the camera is slightly raised, so that the camera lens can rest under any circumstances on the ground.
Mir is the phone fell down until now 2x from table height and has it unscathed. However, the plastic of the casing is very rigid and strong. I think the shell here has no real "cushioning effect" and gives the impact energy more directly on the case of smartphones. It protects itself against cosmetic damage of the cream and the back. However, this was clear to me due to the product feature before purchasing.
In summary we have:
Positives:
+ Very accurately
+ Back imitated the S5 looks elegant
+ Very thin
+ Increase around the camera lens
+ Favorable price of 9.99 euros at the time
Negative
- By the rigid plastic housing should not be all too large, the protective effect when dropped
