There are a few things that caught my attention about that eBay posting. First the price, if it's too good to be true it generally is. Next the auction item you listed is sold but if you click on it you will see others for sale. What caught my eye was the micro USB port, in the photos they show it on the bottom right side, well on Mophie's page here http://www.mophie.com/mophie-juice-pack-air-iPhone-5-p/2105_jpa-ip5-blk.htm its in the middle. So something tells me its not what it seems to be. The other issue is Mophie's speakers has grilles on them and the photo's on eBay do not.

The package says Juice Pack Plus, but the manual in the first photo says Juice Pack Pro, you can't get a good look at the iPhone logo to be sure what you are buying. I would say no go.
