Fantastic wireless charging case that iOS7 broke
It wraps the phone like a glove and will barely add any bulk to it, but it is a good trade off on protecting the screen and sides.
If you still use iOS6, the convenience of Wireless charging is supreme, just place it on a Qi charger and it will charge.
However here is the issue: iOS7 broke the functionality. As soon as you connect it to your phone you will get a message that the connector is not certified and might not work.
When you place it on a Qi charger with more than 60% of battery it will display the phone as charging but it won't and if the phone has less than 60% battery you will just get an error message from the OS and it will not charge at all.
This case might be the single and most valuable loss of the whole official lightning connector enforcement that Apple brought with iOS7.
Even w/o the functionality the case is nice, even nice enough that you might be able to ignore that limitation. I can't.
