PRO Solid design. Tons of diecast throughout the figure. Nothing felt fragile or compromised during the transformation. Cab/feet transformation is really amazing. CON Trailer refuses to tab together, no matter how much I mess with it. Pin on left leg fake wheels kept falling out.

SIMPLY SUPERB--The engineering embedded within this thing is awesome. Of all three third-party Motormasters, this is the only model that incorporates the entire trailer into the robot mode transformation. Mass Shifting, IRL!! HIGHLY recommend
