My LBS has one, I rode it and it was fun but isn't something I would spend money on. For one thing they are pretty pricey if I remember correctly. They are a bit awkward to steer, I remember it being scary to stop and they are huge. For me I am pretty sure the the novelty would wear off really fast.
