Review: Fits with duplo - I really like them My kids play the slide every day. Dinosaur eggs are really well made and fun to play ONLy thing is that instruction is very complicated.
Review: Quite well designed... the marbles stay in motion for a long time - This is a mature product. The marbles spin for quite a long time in the cups/dishes/hemispheres before dropping through the center. The little track with upward-curved ends allows the marbles to move back and forth before rolling off one side. Both my kid and I like it. The last marble run that I used was made in the 1970s; this is much improved. A child might not be able to build much with it until the age of four. My kid is a bit younger than this and can combine components to make objects, but not paths. She enjoys playing with what I assemble, though.
