So I was super excited to get a chance to play with this guy. As other reviewers have noted, he is HUGE and the transforming instructions are pages and pages long. To me (somebody who loves playing with Legos, etc.), this was a plus but I can't see a smaller child ever being able to figure this out. Then again, I've seen a two-year-old do some amazing things with an iPhone, so I may be underestimating today's kids.
Totally fun to transform and play with; there are two figures that morph into the semi-truck so I see some value there. However, the whole thing's made of brittle plastic so you REALLY have to be careful when transforming not to snap something. Pieces also fell off on me at joints; they were easily put back, but it was annoying.
The whole experience just made me want to play with the Transformers I remember from my childhood: die-cast and cleverly designed, these figures were made to last, even with a careless kid like myself transforming them over and over. I don't see anybody wanting to undertake the Herculean task of transforming this thing more than once in a blue moon. So, it's great for a collector who'll keep it in one piece. Not so great for a kid with an inclination toward constructing and deconstructing, as with Legos.
