Review on Dive into Fun with Marble Genius Run Ocean Starter by Robert Abdi

You should have heard a cry of joy when we received this, our girls love it. They built it themselves in about half an hour and have already assembled several new configurations. When fully assembled it measures approximately 3 x 3 feet and can be up to 6 inches deep, although it may take up more space depending on installation. When disassembled, it fits into a large zippered bag. I also recommend having a 50-ball ziplock bag on hand. This is a fun, well-made toy. fall apart if you don't lift and move it carefully. And watching the balls fall is oddly comforting. I can order another one.
