[EX Q]: This was a steal! For 13.00 one would never know it is a pre owned case. It saved my phone more than once when it slid out of my lap while I was getting out of my suburban. The only thing I would change is making a belt clip for it to be worn on your person. Other than that AWESOME!!!! I'm a happy girl.
[EX A]: positive

[EX Q]: Didnt work at all. As soon as I began filling a tube it would shut off (overheating). Wasnt happy as I hade 7 tubes to blow up. Luckily I had a manual one.
[EX A]: negative

[EX Q]: Nice and sturdy! Makes your Night Stand look Elegant. Takes care of all your Apple products! Will defiantly have this in mind for giving this as a gift to friends and relatives!
[EX A]:
positive
