      I am very happy I purchased several of these for my grandsons. They enjoyed them very much.

    • it looked like something my son would like

      My 13 year old who loves LEGO's did not ever want to try this so maybe other boys will have more fun, but not for mine.

      This was given as a gift to a grandson. I have forgotten to check on his satisfaction with the product.

    • As a gift, Good product.

      While I hear the gift is being used and is thoroughly enjoyed, the shipping situation was quite frustrating. Not only that but, our gift message was not included when the gift arrived two weeks after ordering it; not in time for the birthday, as the suggested shipping date proposed. Otherwise, I am told that Sean played with the kit all day, when he finally DID receive it.

    • Great Toy!

      This lego kit has kept my 9-year old busy. He loves it! The writing and instructions are both clear and humorous, and the projects are varied. I love that my son can build a project, then take it apart and build something else. It's not just a one-time use project, as most Lego kits are.
