My only complaint is that the chain that pulls the cars up is hard to get put on correctly so that it doesn't hang up and prevent the cars from moving.

My two sons, ages 9 and 10, love roller coasters and love building things! I thought this would be the perfect toy for them. Unfortunately they didn't have fun with this toy. They found some of the pieces really hard to snap together and once it was built, the roller coaster doesn't work great. It gets stuck, they have to help it along the track, and as a result they have stopped playing with it :(

      Got for my sons birthday. It worked like a real coaster. I was nervous it would start falling apart because it's so big. Not at all. Sturdy and fun to build

              Our kids are primarily into Lego and Duplo, but we saw one of these built at our local children's museum and decided to give it a go. Admittedly, my husband and I did most of the build (and enjoyed it), the finished product is awesome and the kids love it.

                        The K'Nex toy is alright. It's huge. It took me over 6 hours to assemble and once assembled, you aren't likely to take it back apart, simply because it takes so long to put it back together. But, I'd rate the toy a 3 star.

                          I bought this for my 10 yr old grandson. It was a total hit! He had built within a few hours! And then we all had to run to the basement to see the roller coaster go and go! I felt I was in the roller coaster myself!
