Just for fun on my holiday, I built the Kazi 8018 Challenger today. It's closest comperable Transformer is Cybertron Landmine. The Kazi 8018 Challenger has 17 points of articulation, it came with 2 extra bricks, but on the down side one 2x6 plate in the waist was a little loose. I replaced it with another to make him hold together well. Unlike the upcoming Kre-o toys this line actually transforms without disassembling the bricks. Transformation to robot mode is basically turn him over, extend the arms and legs, and flip out the head.
Not a bad toy for under $10 with free shipping.
