Review on 🎢 Ravensburger GraviTrax Marble Girls Starter Set by Jerry Peebler

This was a Christmas present for my 7 year old son. He liked it very much. This is a well thought out toy. Actually it's amazing for adults like me. My son and I have many ideas, such as pairing this product with popular stones (I'm not using the product name here, but you can easily guess). This gives my son an idea of how interesting and important gravity is. The only downside is that it's a bit more expensive. There are some optional parts, sold separately, that are fun to play with, but not cheap.
