I noticed they are doing a big sales push for those for the holidays. My boys had them. They are okay but limited so can get boring. Not sure if he's an outdoor kid or not? Does he already have a razor scooter? Skateboard? When my son was eight he got one of those marble towers where you build different towers and pathways and send the marbles down. Kinda cheesy but had all of my kids playing with it (and dad too!) and you can constantly change the pathway so it's not the same every time.
