[This review was collected as part of a promotion.] First of all, this Mega Construx set is huge. I knew from the piece count that it would be large, but the box is about two feet by a little over one foot. The presentation when you open it is beautiful. There's full color art on the inside of the lid, and a manual that's nearly as big as the box. The pieces are separated into four numbered interior boxes that also have some nice black and white artwork. The manual has huge pictures and more full color artwork. The instructions are pretty clear and use colored dots to help you align pieces where it might not otherwise be clear.
Though I chose this mostly for my oldest child (11 1/2), it is such a big project that there was plenty to do for everyone. In fact, the instructions are divided into five sections that can be built independently of each other, so I was able to give each kid a section to work on independently. (Anyone who has built any building block sets before knows that it's often hard for more than one person to really build at the same time usually.) There were a couple of places where the pieces were harder to attach for the littler girls, but considering the age rating, that seems completely expected, and it makes it more of a family project anyway.
There was good use of some rounded blocks mixed in with the squarer ones to give the walls texture, so that the lack of range in the appropriate wall colors (It is Castle Grayskull after all.) didn't feel too bland. There were neat features to build (like a prison cell and a cannon on top of a tower) and lots of little details (plenty of weapons on racks and a very toothy drawbridge). The figures are colorful and detailed. The quality has been solid. Bricks stick together as they should and the build is solid. Things don't fall apart when you pick them up. You can safely carry it from one room to another without worrying about losing bits.
We've had the set for a couple of weeks now and still are not completely done building it. (I'd guess we're about halfway.) The kids keep going back to it, not getting bored with it as they sometimes do once the newness of a thing wears off. They keep excitedly showing me the next neat thing they discover as they put it all together and make up stories to go along with the figures. They've enjoyed it immensely and I'm glad we chose it.
yes: I recommend this product
