My 3 year old was bought this for his birthday and it has to be one of his most played with toys. The cars are easy to shake and last for a good 4 hours before they need charging. The track is really easy to set up and change the layout. The cars go pretty fast & go round the loop and over the jumps really well. The added accessories of flags & barrels for crash action are a great addition and give them another option to play with. The cars make great revving sounds when you shake them and will even go on carpet if you get bored of the track, which isn't likely given the variations in track you can have. This is much more suitable than a Scalextric for younger children and I would definitely recommend this toy for little ones (and their Daddies!)
