  • About this item

    This K'NEX building set provides kids with the resources to construct a colorful, space-themed roller coaster. It contains 448 pieces and comprehensive instructions, so children can build by themselves, with their parents or with friends. When this Amazin' 8 coaster kids' building set is put together, it stands nearly 3' tall and features two roller coaster loops for the coaster car to zoom through. A motor makes the roller coaster work and keeps the car moving. The car moves up the straight incline, then rockets along the loops and back to the beginning to do it again. Other K'NEX toys and building sets, such as the Star Shooter Coaster and the SuperSonic Swirl (sold separately) can be connected to this set, expanding children's creative possibilities. This set is recommended for children ages 7 years or older.

    I posted this video to express my opinion: http://youtu.be/VtnARiOfLvw Commentary of video by me: Easy to assemble by a 7 year old, provided you are willing to use a little super glue. Works great, and cost only $19.99. Great value for a lot of fun!

    My 8 year-old duaghter loves this! It's not pink and she can use her mind. Instructions are easy to use and intuitive. A bit of a finger challange to connect the ends (my fingers hurt, she was just fine) Overall an awesome buy.

    The best Christmas present

    Customer review by laclay

    I bought this coaster for my 4 yr. old grandson for Christmas. My son set it up easily and it still on my dining room table to this day. My grandson plays with it everyday. The coaster is for ages 7 and up which sounds about right. My grandson has man-handled this coaster-putting things on the track, stopping it with his hands..... and it hasn't fallen to pieces so it's pretty sturdy. My teen sons and their friends play with it too. It was a great Christmas present.
