Picked up Kingdome Prime today and they seem o be the same toy, so here we go. I stated before I wasn't interested, but after seeing hpw good Inferno was, I thought he needed a leader buddy.

Optimus is great, I love it. The legs are too long and dont do anything despite having a hinge inside them, but I assume thats a leftover from Siege. They should've kept the wheel cover for this guy I think. Robot mode is great and loooks cool, is fun to play with and intuitive and clever to Transform.
Top class robot.

The trailer sucks big time though. I really dislike it. It doesn't quite clip together well. Looks too small and the ramp has all this greebles sculpted on so it doesn't work as a ramp andyou also have to crack open the container to drop the ramp too. Who approved That?
The gun doesn't integrate all that well either. It either sticks out a bunch (inside) or conflicts with something somewhere (underneath). Considering how the trailer is just a box, its embarrassing. Also, terrible colour too.
Lower than bottom class trailer.
