Have this circle for my 10 year old daughter bought because it was very appealing at first glance. Unpacked home, we quickly realized that this circle for untrained hands is very impractical. The wheel in the middle allows to quickly and easily make the circles on the gewünschen cmMaß. The downside is that this wheel is not in the position determined bleibt.Es shifts constantly as the feet go back and forth and so the circle does not allow for stability.
