Also, I'm not taking it out of the package for two reasons: It's too beautiful to take out of the package, and the troubles people having transforming Smokescreen. Apparently, you have to remove an axel from the bottom. If I had a second one, I would transform him.
BTW, the difference between the prototype model and the mass produced ones is that the mass produced ones has more of a plain blue paint job rather than the metallic blue shown in the pictures, but still it fucking rocks.
ALSO, you can flip up the hood, and there's parts inside, and you can remove the motor and transform it to an Autobot weapon!
