So I find this totally awesome shell, you do not always lug around a battery pack, but can charge his phone by pressing a button with its own protective case! So I brought my iPhone out of the same old Car and wanted to up the cap on top of it, but this was really hard! I then looked at the manual and tried it out as it was in the flyer, it had then gotten, but it was not easy! I wanted to also do not break anything. Unfortunately, the lower web on the upper cap is broken at the camera, because it is here to mm! But with time and the breach went the lid easier starting, but sat just tight enough that he could not fall down by themselves. Charging works great, but somewhat more slowly than at the outlet, but that is with most battery packs so! But that's not really a disadvantage because you do not have to wait for the battery until it has fully charged at the outlet, but it carries you easily and smoothly around with you while it loads! The four LED's are very important to me, because you would otherwise not see how full the battery shell and thus can also be seen whether the mobile phone in the charging mode or not. The battery can fully charge about 2x an iPhone! The iPhone is obviously thicker, but you used to immediately set. Now, a word about the keys! It is not optimal, because very small keys were used, which are hard to press and it is therefore possible to adjust the volume not as good! When the power button is a bit better, but not optimal. The lower part can be removed also, so you thereby plugged the jack for headphones! But I always take the top off and slide the cord and then sliding the iPhone with back cover and fixed everything! Also worth mentioning is perhaps represented by the shell, which has at the bottom of the front speaker slots and thus sounds even better than without! I was very surprised! :) Despite the knobs and the break I'm very excited about the shell that I no longer want to think away me, because it is so convenient!
