It was a super-duper cool gimmick when I first encountered it back in the 90s... but alas, my G1 Motorvators' gimmick sometimes gets stuck, and the Energon figures do look kinda daft with a giant face sticking out of their bodies (with a tiny head on top!).Also, the auto-conversion gimmick sacrificed any neck articulation; not that this was a priority for G1 toys.
