I have just got a Galaxy S3 recently and I saw at the Telecom store a "4300mah" battery pack for the S3 for ~$45. If I had seen this online I would have assumed it was a crappy knock off battery, but because Telecom is stocking it, I wanted to double check.

Does anyone have any experience with this battery? (I can't remember the brand unfortunately) Any advice?

Thanks guys.
