What can I say? The low price led me to buy and I was not expecting much. Sometimes I want to remotely trigger my camera and the ability fernzuzünden Aufsteckblitze, I gladly with. Both Funkauslöser feel neat, I have rather cheap Plstik expected. You need each 2x AAA batteries / accumulators that are not mitgeleifert. The connection cable fits perfectly on my camera. The remote triggering operates reliably until the thumb in bulb mode can not. If a flash mounted on a receiver sitting widerum on the camera hot shoe, so it is with ignited. Very convenient. According to the manual should also be more than two receivers can work together, each for flashes and the camera. Testing, I could not. Even walls do not prevent the remote activation in the range up to 20 m. Outdoor I appreciate the range of about 30 m. More than enough. The first set Eneloop AAA batteries (1st gen.) Is looking for more than 500 trips still. My conclusion: No cheaper Chinakram but a price / performance tip.
