Summary: The SC-29 is ideal for creating the classic three flash portrait set-up on location. I use the SC-29 to control one flash in TTL mode and 2 more Nikon Speedlights controlled by the remote commander on my D-300. The SC-29 mounts securely to both camera hotshoe and strobe. I have used the product in three shoots so far and it has worked flawlessly. The cord length is more than adequate (if not a little long) for use with fixed arm and flip flash brackets.
Summary: In low light (wedding receptions)and on a bracket this thing is a must have. I would miss the focus on many shots without it. I love it and it works great. HOWEVER, the flash mounting bracket end is not strong enough to support the SB-800 and a defusion device such as from Gary Fong. Mine has broken twice in the last year. You can also bump the on/off switch to off and not realize it right away. I keep a piece of gaffers tape over it and no more trouble.
Pros: Easy To Use, Improves picture quality, Reliable
Summary: I use this product when I am working with out of camera flash with softboxes, it helps to save battery and it is long enough for me to get around...off course it is always better a radio or infrared system but this work for beginners photographers who can´t effort yet something higher or photographers like me which have to deal with exchange problems been in a foreign country.
Summary: Used for indoor events where asking subjects to do anything is impossible and direct flashing can get you thrown out. The on-camera meter is a common sense essential. You are dealing with a dangling wire however and it would be nice to have one hand free once in a while.
Pros: Convenient Interface, Reliable, Strong Construction
Summary: Does exactly what it is supposed to do and does it well. The long cord allows for setting up the flash off camera by a good distance, which is nice. Much easier than setting up the remote menu for the flash commander function.
Pros: Convenient Interface, Lightweight, Reliable, Strong Construction
