My 3 1/2 year old son saw this on TV and received it as a gift. As other reviews have stated, the plastic is a little bit flimsy, but as long as you use the numerous designs described in the instructions manual, the track DOES work and holds up well for us on a hard surface floor (not carpet). My son is now able to put the track together himself after showing him how to connect the pieces properly. He tries to design his own tracks on occasion, but most of the time they do not work properly because you can't get the correct support placement underneath to allow for a smooth downward race. He still races the cars, but pushes them through the section(s) that they get stuck on. He loves the toy and so do the other children that play with it when they are visiting. We think that it is overpriced for what you get. Not to mention that you are going to spend additional money buying the extra cars for racing. It also would've been nice to allow for some creative design in the track layout instead of having to rely on the 5 or 6 designs set out by the company.
