Great fun- hours of play!
My son (6y/o) and daughter (8y/o) love playing with this racing track set. We set up as a very basic track initially to allow the kids to get used to using the controllers. Eventually set up as per the image on the box, which took some time as there are no detailed instructions how to recreate this track. My guess is that Hot Wheels want the kids to use their imagination to build the track as they wish. We experimented a bit with loop the loops and corners etc. Take care not to bend the metal connectors if you are building and rebuilding the track. My kids recommend this if you like building and racing.
