Editorial Review:
Developed in conjunction with the Speedlite 550EX and the EOS-3 camera, this master control device for a wireless Speedlite flash system meets and exceeds professional and advanced amateur standards. Its dedicated transmitter controls an unlimited number of 420EX or 550EX Speedlites as slave units up to 33 feet away outdoors and 49.5 feet away indoors. It is mounted as a clip-on with shoe lock lever and locking pin. Compatible Cameras - Type A EOS cameras (E- TTL, autoflash); Type B EOS cameras (Manual flash) Type - 550EX-dedicated, clip-on Speedlite transmitter with direct contacts
The Canon Speedlite Transmitter ST-E2 is compatible with Type A EOS cameras (E-TTL, auto flash) and Type B EOS cameras (manual flash). The ST-E2 is designed to control slaved Canon 550 EX flashes, enabling simultaneous flash use in professional settings. The wireless controller has a flash ratio control, allowing for several different A:B ratios, 1:8 to 8:1 in half-step increments, as well as slave confirmation via a test transmission button, which sets off slave A, followed by slave B, at 1/64 output.

Canon STE2
I bought the speedlite wireless transmitter and have been using it indoors exclusively. It works great with my Canon 430 EX, even when the reflector blocks the line of sight path.
My only complaint is the battery. It cost nine dollars. It will last a long time, but I would prefer that a more common (Cheaper) battery was called for instead.
usefull, but not perfect
while it certainly does the job of transmitting and metering the flash to an off camera (or two) flash in the eos ttl series (im using a 550 ex and 430 ex, i have also found some of the shortcomings if it. distance in a large room or outside is limited, especially if you are attempting wide angles to the flashes.
it is also rather large and 80's looking. my personal reccomendation is to save a few bucks, and get an additional 550 or 580 flash. that would allow you to still offer the master... more info
works, but has its pros and cons
Does not work well in bright sun, but indoors, and when dark, the IR does well. I shoot weddings and local shows, and lighting is always changing, the Ettl is a must, and is also great as a auto-focus assist (really great in low light).
Very handy tool
I purchased this little item to aid in taking pictures at my first wedding. It worked nicely in a large worship center using both the 550ex and 430ex Speedlites and a 30D. I still haven't used it to its fullest but continue to learn. I'll add more to this in the future but just wanted to comment on this handy tool. A little pricy I guess but what in photography isn't?
