I bought this for my son's 8th birthday as a surprise, he plays out a lot on his bike and go kart and I thought this would be something a little different. I've no doubt he'll be the envy of the street with this! The price was excellent, £50 less than argos/toys r us and arrived swiftly and well boxed. Set up is simple, click handlebars in, and switch on. Ours came with charge already in so it was ready to go. It is heavier than I thought it would be, but I guess this means it is very sturdy and well made. I have had a little try myself and it seems quick. But thats to me, I'm sure the boy will be wizzing about with no probs at all, although I will be sticking his helmet on to use it. All in all, a very good product, for a very good price through Amazon. I wish they'd made these when I was younger!
