I took a chance on this product primarily because it was Uncommon Goods. I'm used to their product quality and knew the product had to be vetted or they wouldn't offer it. However, I had no idea how it worked or what my daughter would think of it. When she saw it, she was captivated by its design and construction. After she used it asked her if she liked it. She told me that you needed to know how to use the wheel so that you didn't put unnecessary strain on your back muscles but if you followed the supplied instructions you would be fine. Within a few days she had mastered the wheel and told me she loved it.
