Ripped the batteries out as I suffer from the same frustrations as LordCyrusOmega:
Yes I know you're Optimus Prime, now please be quiet. This is hard enough as it is
I really don't like voice gimmicks...it's a thing.

Anyways, I have to say this is my favourite movie leader class fig after Starscream and Buster Prime. I have to admit that the transformations of quite a few of the movie figs, impress the hell out of me. Sentinel's transformation is one such little engineering feat that really makes me feel happy inside.

My one major complaint, and this is endemic of the DOTM line, is the real lacklustre paint job. I am totally itching to repaint this guy.
