Today the goods have arrived and was immediately tested. Cell phone plugged in and pressed power button, lo and behold, it invites and does what the part is. The small feet for standing still goes out very hard. In this cover, you can connect the original Apple charger and does not have to be prepared for mini USB and long load times. Dual Load Cell and battery cover seems to be possible. I the super part, because the battery life is doubled now and does not need to be continuously recharged between the power adapter or car charger plug. It is true that on, but if the manufacturers sell permanently installed batteries, have no other choice if it is to be sure the device. I highly recommend it!
