Wow. What an excellent toy. I understand some people's misgivings with the whole size/price thing but the overall design makes up for it.

The core robot and the 'submarine' mode are great as it is, a sweet update of the G1 figure with enough modern design ideas to keep it interesting, but the extra parts add a lot to it too.

The large battlecruiser is badass, and the customisation options are great; there's a stack of different ways to attach the parts to make different styles of large 'battlecruisers'.

I'm not a super-huge fan of Shockwave's 'exosuit', it's nowhere near as well implemented as Ultra Magnus' super-suit, but I really like his drone/hoverboard. It seems really odd that it's featured on the box, but not in the instructions. In my own mind, I can imagine the drone following Shockwave through dangerous terrain, silently watching over him while he does 'Shockwavey-sciency' stuff. It looks really mean, despite being a little hollow.

This guy is a definite must-buy IMHO.
