The Negatives: The primary auto-transform, which is his big selling feature, is on a hair-trigger. This made him a bit of a pain to transform into truck. Plus, the auto-transform still requires a bit of shoulder manipulation. Also, those legs are both immobile and can do the splits. Pretty crazy.
The Positives: Upper body was more flexible and articulated than I expected. His head sculpt is a gorgeous show accurate representation, and his head can pivot! I love his weight. He feels very solid. I can imagine 8-year old me going crazy over the light and sound clips (very short though). The sword and claws are a nice touch, although I'm not a fan of the chest armor. He sizes pretty well with my one large Cyberverse Megatron.
Overall: Good toy. Fun. Probably could have waited for him to go on sale for $45 or $40 though. For what he is, I'm super-glad I got him.
