I've found it to be pretty good, but it took some finagling to get the camera settings right to support it. With the YSD-1s I'm using, I couldn't get consistent ttl firing until the autobracketing control was adjusted for some reason. (It now shows the flash, shutter and clock symbols.) Basically, the tech at Backscatter fiddled with various settings until it worked. You'll need to tell the camera what exposure settings you want, too. There are a ton of choices. I haven't tried it on wide angle yet. Once set, you can shoot rapid fire as long as the strobes will recycle.
My one complaint is that they don't give you specific settings for the camera for compatibility. It would be very helpful to have a suggested starting point. Since it's specific to that camera and a few strobes, I don't think that's too much to ask.
