4 out of 5 eggsextended battery

Pros: Very "Bang for Buck" product. Well worth the price. First run this week gave me 45 Hours without chargring after charging initially to about 95%.

Cons: Lengthy charge time even with the device powered off on 5V 2.1A. The only reason I dropped an egg was lack of documentation though. Google exists to answer questions, but it's nice to not have to research through a bunch of links to answer a simple question about the product.

Other Thoughts: The battery is obvously about double the thickness of the stock one. Back case sticks out a bit more so if you have a specific case you love using just remember it's going away once you install this. It may seem like a nuisance to make your phone bigger, but honestly I and many others fell the phone feels more natural and better in your hands with the added size and weight. I personally feel like it improves it. Overall would recommend so far. Will update if anything changes.

Used on AT&T Samsung Galaxy S3 w/ light to normal usage. (I don't game on it, just text, calls and look up things when i'm out and about.)
