These triggers are extremely reliable with no false triggering or missed triggering. I appreciate that they can use NiMh AAA batteries instead of coin cells or unusual CR2 or CR123A cells like some triggers. Each trigger being capable of acting as a transmitter or receiver makes setup simple and flexible. I can put one trigger on the camera and others (I have four triggers altogether) on flashes; I press the shutter button on the camera to take pictures. The trigger on the camera can also receive a signal from another trigger held in my hand as a remote shutter. Thus I can be in group portraits or shoot while standing beside my camera. I will admit the trigger is a bit hard to hide in my hand so I generally use a different, smaller remote shutter control if I am not behind the camera. I have no issues using these triggers with a Nikon D90 camera, Olympus E-M5 camera, Yongnuo YN-560TX controller, Yongnuo YN560 III flashes, and Nikon SB-800 and SB-600 flashes.

Photography being such a expensive hobby, I love find products that offer extreme value. These flash triggers have never let me down have a great range and are very affordable. Getting your flash off your camera will improve your images and this product is a very affordable way of doing that. Also can be used for a shutter remote bonus

Works exactly as it should
