Rated 3 out of 5 by from Great idea, so-so execution My 7 years old received the K'Nex Clockwork Roller Coaster for Christmas. He really enjoys "building toys", so he was really thrilled to have this motorized roller coaster. I helped him with the build (the instructions are sometime tricky to follow because of the 3 dimensional aspect) and to his dismay, when he installed the last piece of rail, we noticed the cart was getting stuck in the last twist, because it is too tight, so the motorized arm can't push the cart by itself. I had to modify to try and make the twist a bit less tight but haven't been able to get it to work completely without needing to push the cart by hand so the motorized arm can then grab it and push it up. Looking at the other roller coasters from K'Nex, I have a feeling the models where the motor is on the rail itself (like the Hornet Swamp or the Inferno) would probably work better than this model. All in all I think this toy is a good idea, but the execution was a bit so-so. I'd recommend getting another one of K'Nex roller coaster models.
