Excerpt: Mount is structurally weak, broke after light use. After the fourth time I used it, the plastic slide fell apart during a wedding shoot. Was able to rig something using wire and duct tape, but for the high price, thought it would be better quality. The cord synchs great, but the weak mount renders it mostly useless if you want to attach it to anything like softbox/tripod.
Excerpt: Just had my 2nd OC-E3 fall apart in a 3 month period while on a shoot. I have stayed with only Canon products for over a decade. Unfortunately, Canon refuses to look at the issue that is going on with this cord. If you google it you will see images of this cord in pieces. Luckily I was able to catch my flash when the first one fell apart. I had to switch to the Vello TTL cord. Took it out on location yesterday and it did a beautiful job.
Cons: Difficult To Use, Falls apart, Not Durable, Not Functional, Poor Design
Excerpt: The original cord we bought had the metal contacts break on it. We had to buy a replacement. The cord wasn't removed and replaced very much. It pretty much stayed on the camera all the time. Really surprised when the contacts broke. It had lasted about two years though.
It's a great tool, but a little high on the price side

Summary: I recommend this tool for off camera flash, but it is a lot more expensive than the 3rd party alternatives. The quality is top, and it's a very stable system. You won't worry about your equipment falling because this breaks. That is a concern with the 3rd party equipment. So the bottom line is it works well and it's the most solid version of a shoe cord you can buy.
