The product was delivered quickly after ordering. Unfortunately it does not work as specified in the product description. In my case I was looking for a radio trigger for Canon EOS 400 D and EOS 5D MKII. For the former camera and a flash of the remote trigger device triggers easily. The EOS 5D MKII can not be operated. The selection of the distributor to send a second cable, unfortunately, was not effective. The telephone support from the staff of the distributor but was still very friendly, helpful and outstanding. The hot-line seller (Photo Eberhardt) could not be reached on various business hours. Large lack: the product description should be meticulously scrutinized so that they correspond to the facts and the customer can leave you 100% conditioned it.
