I own this case. It’s the 3rd battery case I’ve gotten for my iphone 5/5s. This has been the best so far as well. It doesn’t provide the best battery life compared to others on the market but that’s due to the fact that its a lot slimmer. That’s OK by me though.
Ive had one, or one like it for some time now and its awesome. Charges back up 80% pretty quickly. LOVE IT!
Helium?
