Very fast delivery. I asked the seller questions and answers were fast. The seller is friendly and informed us of the status of the command in preparation ... ... dispatched date of delivery ... I was very pleasantly surprised at the quality of this flash, that's neat. It is a clone, with very little detail closely, almost perfect from that of Nikon SB900 I already own but did not cost him 115 but 450. Mr Nikon Sorry, I tried to be faithful but then I does little more, it is the crisis. I conducted some tests and apparently no problem: tested on the hoof and slave. Plus: there is the soft box to the flash, color gelatins and adapters for clogs or remotely trigger your camera or your flash if your device is not equipped (I have the D800, it works without ) .It lacks the diffuser cap. Very happy with my purchase and it allows me to set up a small studio to begin.
