Great product, works as expected!

Très bon compromis lorsque l'on n'a pas nécessairement le budget pour un modèle constructeur.

Works like a charm. Easy to figure out. Radio control beats IR line of sight systems every time. Inexpensive. You need to own this if you want to be able to use multiple Yongnuo flashes in a setup. Great value for money.

For the money that I spent on this Flash. It was a Great Deal. Such a Great Deal.

I use this with 2 Yongnuo YN-560III mounted in soft boxes, along with my Nikon D7100. Super easy to use, and to adjust each speed light's power setting remotely. I just take the 560-TX off the camera and carry it with me when metering the subject. Simply position your flash meter, fire the "test" button, and you've got your reading. Then head back to the camera, put the remote back on the camera hot shoe and I'm all ready to shoot. The only tricky thing is syncing the 560-TX to the speedlights.

This Product works exactly as advertised, I have four YN 560 III's and had no problem activating the group function from the 560 TX. The YN 560 TX works with my yn-603 as well.
