Great for off camera flash
This set is designed for using your flash/strobe off camera. The transmitter part goes on the hot shoe of the camera and your flash goes on the receiver part.
They have multiply channels so if your mates have the same set you can use different channels not to affect each others gear. Or any number of you with the transmitters could use the same flash set up if you want.
It's really simple to use.
Note this system is not ETTL your flash needs to be used in manual mode, nor can you alter the flash power from the transmitter like the much more expensive systems.
This is a budget system, and it works great. I'd say the range is around 20-25 meters, plenty far enough for a home studio set up or a model out doors. It's small and light. Mine lives in my camera bag with a small (12 inch) softbox gadget I got for a few pound also on ebay. Bung the flash on the tripod, pop the softbox on and I have quick easy nice off camera lighting.
For the money it's a great deal.
