Not a success.....,
Verified Purchase(What is this?)
This review is from: Mophie Juice Pack Air External Battery Case Made for iPhone 4/4s in Black - MFi Approved (Wireless Phone Accessory)
It is not a very good fit. It did extend the battery life for a reasonable period when it actually worked. It has now stopped working completely and I am trying figure out how to return it.
