Have decided to use this flash because it does not seemed too expensive. The presented features correspond to the device. Easy to handle. Works flawlessly. He has a small flaw, however: There is nowhere a German manual! That's too bad. The name "Meike" seemed to be German, had previously not informed me, but is a Chinese brand. But that does not detract from the performance, it is well made, fits with the corresponding camera. Property me can be explained by a photographer, the device, so all were understanding problems from the world. Super part! / Recommended / 5 Stars!
