Query: Poor quality

I bought this racetrack for my 6 year old son because it was the only one I could find in the town I live in. Lesson learned. The cars can't stay on the track long enough to entertain the kids for more than a few minutes. The contacts are poor, so power is constantly interrupted. You need a third person just to put the cars back on the track and give them a boost when they lose power. We're also taking it back, and leaving town in search of a quality track.
