Review on Hubelino Marble Run Award Winning Compatible Learning & Education by Gary Shakeone

This is a wonderful product. I don't have Duplo, but I believe Hubelino's claim that they are fully compatible. The bricks interlock like a popular brick brand and form a very stable structure. The curvature and geometry of the track's elements are carefully designed, and the hollow plastic balls roll easily along the track. The barrel elements in color and the brick structure in white create a pleasant contrast to the structure and make it easier to follow the ball run optically. For this reason, I would recommend purchasing additional white Hubelino bricks. Additionally, their Brick expansion kits offer Brick sizes best suited to the Hubelino structure. Of course, expansion kits with additional functional elements make these races even more challenging. Note: There is limited but sufficient geometric compatibility between these stones and stones from a smaller well-known brand, so it would be interesting to design an automatic ball loader for the Hubelino marble route.
