I own the battery case of anchor for my iPhone 5S. After some testing, I can say that this pleases me well. To attach the iPhone to the sheath, is necessary to remove only the plastic frame. That's easy. Then connect iPhone to the Lightning connector and attach the frame again. So the iPhone keeps well in the shell and fits perfectly! There are no gaps, but also no tension. The frame is in black / transparent and transparent and can be applied depending on your preference. The speakers are to be used through openings yet. It is a bit difficult, the keys (except for home button) the iPhone to use, but works! There is no longer accessible by any headphone jack through the shell of the jack connection, is especially at a small extension cord. So also the Connecting headphones is not a problem! The sheath is due to the battery of course a bit difficult, because the plastic material of the outer shell but completely okay. The plastic also does not feel cheap. Only the fold-out stand to set up the iPhone at an angle, feels not quite stable. Good also the power button is combined with the LEDs indicating the battery charge level of the auxiliary battery. The camera can be used without any problems.
Overall, my battery case like super and would highly recommend this!
