Review on Enhance Learning & Education with the Hape Quadrilla Wooden Construction Set! by Govindarajan Diepenbrock

This is a great addition to the Quadrilla set. I wouldn't recommend buying the kit separately (Vertigo, Challenger, or Autobahn are great starters). The important elements are 6 music sticks with 6 yellow blocks or red boosters to attach to the music sticks and, my personal mother's favourite, the marble trap! the old man didn't like the musical component. Our 3 year old is showing some sensory issues. The rhythmic sound of the balloons has a calming effect, but the musical beats irritate his senses. I would not buy Music Motion for a sensitive child.
