Review: My 2 year old loves this set. He is always excited to see the ball run and loves to drop balls and watch them roll down. As parents, we love that the toy is not only fun, but also educational as toddlers can learn about cause and effect. It also encourages them to use their imagination, when they start using the bricks for their own creations. This toy can not only be a ball run, it can become a playground, a house, a garden, a farm.... it is compatible with Duplo, so my toddler brings his Duplo animals over to play on it. I can see this toy keeping his interest for a long time. Highly recommended!
Review: This set is super fun. Kids and adults love it. I wish there were more pieces that twisted the other way. Makes it hard to make a long slide because it folds back on itself so much- needing more height and long straight pieces. Also I think the house walls are AWESOME! but I got two of the same kind- so they don’t fit together.
