Perfect There's no better

I bought the battery grip a few months ago and this at last weekend (10/18/2013 - 10/20/2013) times properly tested through its paces, in short, I was on a metal festival. It was not exactly squeamish to the point (some of the amateur photographers know that perhaps), the camera does all the best survived (Nikon D3100) and the battery grip also to the small jack. This is not broken but the jack goes out very easily, I have to fix it in practice with some tape. Despite all I have to say that this battery grip Meike super is, would buy it immediately. My batteries hold since then without problems at a time when very low light conditions and even some with lightning over 700 pictures, though I must say that my objective up to a maximum aperture 3.5, since it is sometimes already on testing the settings and the costs also battery again.
