Review on Enhancing Creativity: Marble Building Classic Compatible Toddler by Greg Mahoney

This is a great marble run set and my 6 year old loves it. We both appreciate the included booklet which has step-by-step instructions on how to create 4 different tracks. My daughter feels really successful when she can do it herself. She told me she enjoyed building them more than watching the marble crumble. The best part is that in addition to being very solid, the pieces are the same size as their duplo blocks, so we can add them if we want. (See comparison image of white bricks and pink duplo.) My husband and I also enjoy building with this set so it makes a gift for all ages.
