Pros: Charges quickly, compared to others
Over double the standard battery life
Easy to insert and remove iPhone
Feels nice when holding it

Cons: The only bad thing that I can mention is that the two parts that snap together don't seem as if they will stay snapped together with a lot of handling but it's held up so far. Time will tell how this will work out.

Glossy Finish but it's not too bad and some may like this.

Other Thoughts: I'm actually surprised by this battery case because it works very well. I was not expecting this for the price. I've had others that cost triple the price and they just feel bad or are slow to charge or have issues with just working and staying together. I even own a couple of Mophie's and I think the quality of this case is better than the Mophie's. The Mophie's costing nearly 10 times the price! Time will tell the quality of the internal battery but even if it's bad it's not too expensive that you can't just buy another. So over all 5 stars!

Also note it does something the Mophie does not. By holding down the little button it turns off the charging transfer! That's great so that it does not constantly slowly drain. It's a gem and a keeper in my book!
