I've attempted to use the Adorama cord attached to a Stroboframe and 580EX II with my Canon 30D for several weddings and it makes the flash mis-fire or flat out fail. It may take 3-4 shots before it requires jiggling or re-seating. It's not a reliable piece of equipment, however the customer service person at Adorama was gracious and advised me to send it back even though it's past the normal 14 day return period. He will be replacing it with an original Canon cord, and I'll be paying the differnce in cost.

Got a new Canon 580EX II flash attached to this off-camera cord and well it worked for a few shots then nothing. If I lock the flash base (ring at the bottom) then flash never fires, I have to unlock the 580EX II and fiddle with it (left & right) until it works.
Finally I ended up putting the flash on top of the camera till I buy a genuine Canon OC-E3 cord.

I bought this with a Stroboframe flip bracket to use as fill on a wireless setup using two 580 EX ll flash heads and a 420 EX as hair light.
It felt flimsy from the first time attaching. You have to tighten this thing to what feels dangerously tight as it is cheaply made in order to keep it from rotating with the flashes weight when flipped to portrait mode.It worked ok for the first couple of days, and then I started to get bad connections with the flash to camera (5D)
THe flash was jumping into TTL instead of E-TTL, setting were changing all the time, the camera was not snapping sometimes. I was hoping it was not one of the new 580 EX ll that was going bad. I mounted the flash head directly to the camera and all problems were gone. A bad E-TTL cord. Don't waste your time with this as you can see with the other reviews.

Tried this on a 20D and a 5D with a 420EX and it wouldn't work with either one. They didn't recognize that a flash was even attached. Tried it with a new 580EX2 and got the same results except the 5D fired it but only on manual. Am going to try to return it and get the Cannon one. Wish me luck!

I bought this as part of the 580 Ex II deluxe package and it worked pretty well, but when I put it in my bracket and flipped it so the flash would be hanging in the shoe instead of pressing down (like it normally sits if you're shooting horizontally) it stopped working. It seems like the weather sealing of the 580 EX prevents it from sitting flush against the mount.
I ended up buying a Canon OC-E3 and that works fine.
I would recommend this to someone who doesn't have a 580 EX II. I gave this cable to a friend with a 550 and it has worked fine.
