Loved the physical adaption to this 2 wheeled balancing act. Easierthan it looks. In fact after 15 minutes you're not even thinking about what to do. It became intuitive, all you had to do was think and it responded to your thoughts. So cool. I want one. Crusing through SF was safe with our capable and knowledgeable guide. 2 Hour dream time. Definitely will returnfor this one.
