I usually struggle with complex transformations, but found Jetfire to be a fairly simple process, though still taking me a few minutes. The more I play with him the more I love him, so much so that I bought a second from Amazon so I have a separate Jetfire and a separate Skyfire. For anyone who missed him and was waiting for a non-existent retail release (THANKS NZ FOR TAKING OUR STOCK) I'd highly recommend getting him online such as amazon.com.au
It's going to be a holy grail toy that people will chase after in decades to come.
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
