My children (3 and 5) got these for thier birthdays. They were initially great, but the battery packs fell off them, and had to be taped back on. Then the wheel fell off my daughter's scooter. We have been advised by Ozbozz that we can return them to be fixed, which we will be doing. They have just a six month warranty... They didn't not fold very easily, and were just not very durable at all. Great fun, but not for long.
