This sturdy toy is providing hours of fun for people aged 3 to 25! The track is easy to reconfigure and holds together well. The only drawbacks - the large cars gobble up the batteries quickly and the small vehicles do not work on the tracks - but they are friction operated so are a lot of fun on the bare floor. As another reviewer experienced, the roundabout broke right away and the instructions say not to use rechargeable batteries so only 4 stars but the kids are loving it!
