Summary: I bought two of these flashes for off-camera usage with my existing Cactus v4 triggers. They were shipped fast and performed awesome. I haven't had to put through a rigorous test but they worked great for a recent wedding.

Summary: Clever capable and reasonably priced from the purchaser I bought it from. Although I am still learning how to pilot thing it has a zoom function which allows you to adjust the focal length on the flash you can network up to 4 of them together if you want a floodlight effect through a set area. you can set its intensity for when you want to limit the brightness or run a strobe effect.
Great, reliable, cheap flash - Awesome for the price!!!

Summary: I have two of these for my off camera work, but have been perfect so far. Because they are relatively cheap, I haven't babied them in the least. So far I've used them with both shoot through umbrellas and soft boxes while having one RF-603 on top of my camera and it's worked flawlessly!
