HOT WHEELS Wall Tracks Glow in the Dark - Downhill Flip Drop

The item is OK. My son is very fond of car toys and has a lot of hot-wheel cars. But most of them won't run smoothly in these tracks. The car given with the tracks works well though. Also, it is slightly clumsy to install the tracks on the wall. The 'Glow in Dark' is useless; it has to be complete dark if you want to see the glow. My son stop playing with it after a week.
