Bought these when I purchased a YONGNUO OEM YN-560 III speedlite. Great little wireless units and they even work with my studio flash lights,which I was hoping for as I wanted to ditch the cables so I had more freedom on shoots. Would recommend these to anyone looking for a wireless system.
Bought this flash to use on my Nikon as I wasn't keen on spending a few hundred pounds on a Nikon unit. Was very pleased when it turned up and was quite surprised when I took it out of the box as it looks a lot more than it actually costs. Would recommend this flash to anyone. Would also recommend buying the RF-603 Wireless Flash Trigger as well to use with this flash.
