I am not sure what happen to toy manufacturer nowadays. The quality control is not as good as last time. A product should get improvement over time. It's masterpiece but the quality disappointed me; I guess not only me. I just viewed a review done by Optibotimus, it seems the recent released of new transformers masterpiece quality isn't that good. Plastic easily get snaps while transform. The plastic really look thin and flimsy for a toy that needs transformation. You may view the following video for a clearer "picture".
