Despite the negative comment from a previous guest, I let myself be convinced by this product. I thought it was an original Samsung battery. Now it is not so, that my battery was delivered, albeit in a normal quickly coli was packaged in a small plastic-bag, without any information on the packaging of SAMSUNG. Nothing to do with the plastic-rigid packaging and stamped SAMSUNG recorded pictured on the site selling AMAZON !!! Disappointment of how this battery will discharge at great speed and confirms that it is a pale imitation of the original.
