Very fun activity with easy to follow directions I did receive a broken piece in the package but I was still able to complete it.

Great build kit!
My grandson loved it! Gave it as one of his 11th birthday gift. My daughter loved the “no screen time” activity so a real win win.

My son was super excited to spend his birthday money on this roller coaster kit. He put the whole thing together according to plan, but it doesn't work as promised. The car will not make it around the loop. We have researched it online and it looks like a lot of people are having the same problem. We have tried to modify it, lubricants it, and even add parts. Nothing works. Such a bummer for my little guy.

Great product, poor shipping
While I do recommend this K'nex set, I would order through a different source . I bought this for my nephew's birthday and it was shipped in a bag rather than a box. The result was that the K'nex box was smashed up when it arrived. The contents were still intact, but I had to tape up the box before wrapping it as a present. It made my present look used rather than new, which I was disappointed in. He was still excited about his present, though. It builds three projects that are written out with the directions and it comes with a motor.

Got this for a gift and it was disappointing. The car couldn't go on the roller coaster as advertised.
