Pros: Superior build quality
Cons: no focus assist
I used the ST-E3-RT with 3 600EX-RT flashes for a wedding reception and loved the ease of the system and the results -- that is, when I could focus.
There is no focus assist beam when the radio trigger is on-camera, so as soon as it gets dark, focus performance diminishes significantly. You then have to mount one of the flashes on-camera to get improved focus, which defeats the whole purpose of off camera flash.
So, the radio system works best when you're trying to create some fill in good-to-average light situations. Once it gets dark and you want to use the system to create off camera light, you're out of luck.

Pros: great build quality, good value
This is a product I have wanted for a long time, and it works very well, but......
It should articulate like the flashes do, meaning go from the flat position that is currently to a screen up, vertical position so it can be read when the camera is at an eye level position on a tripod. I would like to see this change made in a new product. Very frustrating to have to either remove it from camera or remove whole camera from tripod to change settings, or carry a small ladder to be able to see the screen while it is mounted to a tripod. Just my 2 cents. I own a lot of canon gear including four (4) 600 ex rt speedlights which I love. Make this product go from good to GREAT! You can do it.....

Pros: quiet, Good Exposure performance, Superior build quality, Fast recycling time
Cons: no af assist beam
Everything works great except No AF Assist Beam. Need that beam, put that in asap. The main flash 600EX-RT must be mounted on the camera at all time at night time, so what's the point of buying this ST-E3-RT then?

Pros: quiet, Good Exposure performance, Superior build quality, Fast recycling time, convenience, same display as 600 flash
Also have a single 600 flash. Wish they had an adaptor for my 580 flash. But great for getting rid of the cord for macro, hand pointing the flash, remote location of flash. I will be adding at least 1 more 600 flash to the arsenal.

Pros: quiet, Superior build quality
Cons: no focus assist, large investment, can't talk to radios from the past, only 100' range
Canon had a winner with the older ST-E2 but is a bit short with the new radio transmitter ST-E2-RT. The omission of the focus assist light is major. My Canon 5D Mark II and Mark III cameras can focus well in daylight, but a dark room it is a challenge. The cameras just miss too much without a focus assist light. Canon omitted this feature and any other maker of radio transmitters also has no assist. So Canon has a great radio tool that may not deliver focus. As well it would have been better if we could integrate the ST-E3-RT with existing radio products. We have owned other radios for over 15 years. Some older receivers are built in our studio strobes. But the Canon will not talk to the current studio equipment.
It is unfortunate that the Canon product has been priced at level higher than we've paid for radios with no cross communication. And no focus assist at this escalated price. Canon acts like they invented radio transmitting, but really we've been fighting line of site for a decade. We bought the new 600 flash system, but it really talks about Canon not understanding the studio photographer's big picture.

Pros: aa batteries
Cons: no hot shoe
Right out of the box, it performed exceptionally well. This is a long over due product that filled a gap that was provided by third party manufacturers, that tried to please everyone. This transmitter excels in the following points:
1-Controls the speedlites in both ETTL and M modes.
2-Controlls multiple flash groups, which opens the possibilities to infinite amount of combinations.
3-Eliminates the need to touch the remote flashes.
4-The most amazing mode of all is the stroboscopic, with multiple flashes on different group ratios.
5-Easy menu, with beautifully back-lit multi-function LCD, is located right on the top.
The Only Drawback is: It doesn't have built-in HOTSHOE!
that was a mini blunder! but i could live with that.
Enjoy shooting, and shoot hard!
