All of my kids have had one of these scooters. We actually just bought 3 new ones because they literally loved them to pieces. Okay, okay-so it was the truck backing over them that made them into pieces but my kids can't get enough of them! The roll easily but don't seem to let the kids get going so quickly that they're out of control. One of my kids has some proprioception and balance issues and I was worried this might be too much for him. He never crashed and this has actually helped his balance and leg muscles as well. These are awesome!
