I got Dinobot. Aside from the colours, he is a rather good toy. Both modes look good (the dinosaur looks like a genuine dinosaur species), the robot mode optional claws are fun, as is the faction insignia and the sword/missile, and overall it's a great toy.

The instructions say to turn his dinosaur arms up onto the tops of his shoulders. I don't do that, since in my opinion it looks rather messy (it doesn't nearly have the effect of, say, Prowl's door wings) and detracts from the rest of Dinobot's appearence.
