After I was able to test the product for a few days now, I'll give it a review. But I will start with a negative point, but the seller may not, but the Hersteller.Es for this product are no German manual, but I found a video about this product, it refers indeed to a superior product, but by the operator here everything is the same, see the link listed. [...] The timer remote cord corresponds to 100% of those listed here, the processing is OK, the operation easy and understandable (I looked at the video and worked simultaneously with the trigger and my camera). The interval control works perfectly, focusing on the various ways of using this product is gegeben.Der Kabelfernauslöser is very good in the hand, is easy to install the connection cable is sufficient for a pleasant working environment. The product and the seller, I can recommend without any problem, the delivery was made within the specified period. I admit for the product 4 stars, a German manual would be available, so I could give 5.
