What was all included cable wise, another accessories?
--Box (torn up courtesy of US Customs)
--User Manual (English / Chinese)
--A pouch of reasonable quality -- Seems to be woven nylon, neoprene lining, a touch of pleather trim, velcro
--C1 shutter release cable
--C3 shutter release cable
The shutter release cables connect to the device's multiplexed miniusb port.
The hotshoe adapter is made of mostly metal, and it has a rubber weatherproofing gasket around it. It looks pretty similar to the 600EX-RT, although there is a bit more play overall in the mechanism.
--MiniUSB cable needed to upgrade firmware
--A stand (pictured in many of the product images released by yongnuo)
Also, I realize this is a photo forum, but excuse the crap webcam photos.
