I opted for this battery for a price-performance ratio. I wanted a S3 battery with more capacity and at a good price. The battery was the day after my order already there, great. I have this loaded immediately upon receipt and must say, the holding really super long, even longer as my original Samsung battery. So it must be, if you ordered online articles. I would highly recommend this battery only continue for those who want a new set up. In addition, it was very strange to me that the original battery from Samsung is offered with price differences of up to 15 euros. So I thought, rather a different manufacturer have not been disappointed at a single price, and am.
