ThinCharge - World's Thinnest Battery Phone Case for iPhone 7/7+

I have the iPhone 6 version and totally love it, using it right now

Have to invite friend to get 50% off. Message before sign up was misleading.

How much will it cost and how long does the charge last?

I was one of the lucky ones that got the one for the 6s. Best battery case in the market.

What are the dimensions?
