I don't see the point. They are just basically over priced hotwheels with pictures on the bottom.
I like Transformers toys because they transform and have full representations of the characters, not just their alt modes.
If I wanted die cast cars I would go and find the box of old ones I have laying around somewhere, there's no difference to me really.
Maybe if they were alot cheaper then I might not think they were as bad, but either way they arn't my cup of tea.
