My grandchildren liked the two items that were similar. They just need more challenges with those types of things.

I bought this for my 9 year grandson who loves to build things. I hope this will help him become the engineer he dreams of!

This was a birthday gift for my 12-year-old grandson and he loved it. It was challenging and fun for him to assemble Quality all the way through.

On visit by grandchild, this was first choice. Properly challenging; great opportunity for child and adult to work together and discuss what makes a building project strong. We looked at pictures of Roman arches, of the Eiffel tower, of ancient and new projects. Super project.

My 13 year old son really enjoys this. Only downside, and the reason for 4 stars, is that the pieces are plastic; not metal. The picture on the box makes the pieces look like they’re metal, but they aren’t. They aren’t made of cheap, flimsy plastic, though. They’re quite durable and have plenty of flexibility. Overall, we’re quite satisfied.

The age range says 8 and up, but my budding 5 (almost 6) yr old builder loves it. He needs help putting some of the pieces together and especially taking them apart, but is increasingly learning to do so on his own. So far we've built the eiffel tower and the ferris wheel. They're remarkable structures--engaging, attractive, and remarkably illustrative of the power of different shapes in architectural enginneering.

Clear instructions and several projects in addition to the ability to design your own projects! My grandson, 10, loved this gift. Some of the parts were missing, and one phone call got us complete satisfaction.

My grandson prefers the Lego direction. This was not the quality I expected for the price.
