We took this product out for it's first spin and found ourselves instantly disappointed. The idea was to run it on the concrete drive with chalk. However the teeth of the plastic spirals would not run within each other. They'd continually slip beneath or over the outter ring. We could not use it outside. We took it inside and found some crafting paper and felts. With this setup we could create a messy spiral, however it took three of us holding down the edges, and still the inner circles would slip beneath or over the outer ring when the pressure wasn't just'so. A truly awful product we will be returning.
