Just opened mine (TT version) and yeah...what everyone else has said.
Wow. I'm enjoying him more than MP Prowl.
Robot mode is amazing, car mode is pretty good aside from the gaps, and helicopter mode is OK. All things considered this is an incredible piece.

Really glad TT altered the colours from the first shots we got - he's not as bright as the Hasbro version but he looks vibrant enough that it works.
