Battery life convinced BUT ...

In itself, this case fits perfect but the upper part of "snaps" not in the larger lower part, so that you have to give it a drop of glue, so that it holds. Unfortunately, that's a problem, because one might want to change the SIM card and then you have to rip out the upper part again. Unfortunately, my son took this case very badly for a school trip, so I no longer send it back and exchange could but apparently I'm not the only one who (with no right einrastendem shell) obtain a Case. Too bad, per se, the case is really visually and technically managed.

UPDATE: Unfortunately, the surface dissolves, especially at the edges, after little use on (!). Obviously not a good quality.
Even the loading via Lightning cable is a problem because either the battery is not charged or when the iPhone is not loaded, depending on your mood. The battery itself is not bad but as already mentioned is the weak point on the surface quality and the "snap-in" mechanism.

My tip: I now have a Mophie battery case for the iPhone 6 bought my son in the US at BestBuy, which is absolutely great. The quality is 1A, the battery lasts a long time and also though charging via microUSB is done, so you can switch the battery via on and off, which is a big advantage. Clear recommendation but apparently not yet available in Germany.
The weighted here Powercase Ultra Strong has traveled the same in the (special) waste, because the surface had already been solved clearly.
