I received it a few days ago 2 copy of this battery. Well packed and delivered with a small manual, it inspires confidence. At the reception it was already loaded, is a good omen holding of the load over time. Auspicious because the manufacturer announced that it is not preloaded. No compatibility issues with my Nikon D5100. The icing on the cake is announced at 1200 mh while the original made in 1030 mh, so better than the original.
