As parents we thought in principle this was a great idea, a portable scalextrix that you can set up and pack away in moments. In practice this was not the case. The connectors on the base of the cars are so flimsy that the cars do not work well on the track, every few seconds you have to keep repositioning the cars as they lose contact and stop working or come off the track repeatedly . It wasn't a question of driving style or driving speed which we understand can make cars fly off the track round corners, it is just poorly designed.This was a Christmas present and my 6 year old sadly commented that "Father Christmas didn't bring us a very good scalextrix Mummy". Disapointing and not worth the money.
