Here's my quick review. Don't waste your money. You get what you pay for with this one. I gave the batteries a couple of cycles, and they don't even last as long as the original. As soon as the charge is at 100% within 5 min it drops to 95%, and then a steady drop after that. Both batteries are the same, so it's not like one is bad. The original can last much longer. I've had extended batteries from other companies, and these are by far the worst. My top two are Mugen and ZeroLemon. Stick with those brands.
