I picked up this transforming brick set on ebay for about $13 with shipping. Although sold by Chinese brick company Sluban, the design is "borrowed" directly from Korean company Oxford Block (makers of Kre-O!), as part of their Special Police Z-Force line. The only differences I see are a few small color changes and the shape of the wings. The bricks are high quality. Comes with several parts that are unique to Oxford's design, like the ball joints later used on Kre-O. It comes with labels, which I have not appilied yet. The set came with a Mini-Figure, I added the Kreon Starscream for fun. Jet mode is obtained done by having the wing pulled out, the arms folded against the cockpit, and the legs laid under the cockpit like skies. The funs rotate, and the canopy hinges up. Robot mode done by having the arms pulled out, the legs straightned, and the wings folded back. The pictures place the knee joints coming from the back, resulting in the robot being lopsided. I came up with my own let configuration, which I think is probably what the designer had in mind (as opposed to the guy taking the box photos!) Another little feature seen on the back of the box is that this set and the other two of the series (also KOd by Sluban) can be assembled into a combined form.
