My son (2 1/2), daughter (5), and I (34) have had a lot of fun with this inexpensive little track. Lots of head to head racing with our favorite little cars. The racing is good for one lap only. You can keep them going by re-cocking the launcher in mid-lap but it takes more effort than its worth and you miss watching your mini car race around the track. The cars that come with the set, zoom around the best. We bought a pack of 5 Vettes which look cool but crash more often and sometime don't quite make it around. We haven't quite figured out the advantage to the speed dial although some cars get around better on a slower setting. Good amount of fun for not much money.
