After I bought another wireless remote release, the (when switched off !!!) and thus as a "money-eaters" turned out to be "batteries-eater", I have now bought this product. The decisive factor was that this device is equipped with ordinary AAA batery that cost very little and to have all Video- for a big +. The function of the device do I rate only partially, as it so often was not yet in use. But for far few missions I can say that everything works absolutely top and the connections to the camera (Sony A35) 100% fit. This is also a + - should later turn out to have any (Chinese) electronic quirks, I'll announce it. My advice to all interested parties - take care of the power supply (type of batteries). There are basically from me a buy recommendation.
