Already when unpacking it was clearly shown that the direct packaging of the battery / cover was crumpled and pressed part. The tab for opening was torn and worn out, as if the package had already been opened and closed X-time.
The Case / Battery part made when I held in his hand a stable impression and looked chic. Had imagined a heavier and wuchtigeres part. Yes, it would fall from her appearance. But here something was damaged. Inside part rattled around what the first positive impression made naught again. That was not at all.
It was the Case / Battery neither description nor in guidance. The two existing switches were misleading. With the touch of a button with the usual off / on icon apparently was only the battery level check. There were three estates symbolically shown that glowed under pressure. Accordingly, the battery was full. On the bottom is still a slide switch with ON / OFF. It can be assumed that it turns off the function of the battery or. Exactly, I can not say but lack of description.
Have not tested, but returned immediately the Case / Battery. Too many flaws.
