Review on 🧱 Classic-Compatible Toddler Building Set: Versatile and Diverse by Garrett Flores

This is a great way to combine a marble run with Lego. My 3 year old daughter loved the toy so much that she started doing the orbit as soon as she opened the box. The funnel-shaped piece is more difficult for them to build, but interesting to look at. It is compatible with Lego Duplo. One small flaw that we don't like that much is that the building blocks aren't made to fit as well as Lego duplo. For example, a spinning gear wheel doesn't spin as smoothly as a similar Lego duplo.
