Just picked mine up from the post office! They're pretty cool. The youtube video I filmed is here: it contains the head being used on various headmaster bodies! There were no instructions in the box, though the bottom of the box claims there are some. There was also an extra piece (a plate) that fell out of the box.. It has pegs on both sides that you peg it into one JB toy and then the other and that's how you get the super deformed head thing going on (in a manner that it won't fall off the toy. I found the optimus prime one works better with the existing headmaster toys. Soundwave's head is a bit wider and was harder to plug into the headmaster ports.. So I cheated on my video and just placed him on top (you'll see me struggle) I'm editing and uploading my youtube video now.. But for now enjoy some pics!!
