I bought this set along with the Yongnuo YN-560 Mark III lightning. Thanks to the screw of the trigger bomb holds on the camera. In the first version, I would not have bought the trigger. Only pushed into the hot shoe does not last really good. He makes a stable impression and is reliable with the flash of Yongnuo together. But also in use as a transceiver for my Bowens 500 C Blitzanlage I had no problems so far and work reliably with the system than with the very error-prone Pulsar trigger from Bowens. The supplied Camera Remote Switch for Canon fits on my Pentax K200. This allows the set to use as a wireless shutter release for the camera. Both switches are brought into the TRX position. The buttons of the transmitter can be used like a camera shutter button. Press to focus and Pressing for triggering. Only a Stativschraubanschluss would be awesome. So for the price of five stars
