I ordered this for my 4 year old girl to help her learn Cause and Effect among other things. It has great chunky pieces, smooth edges, warm pastel colors, and well put together contraptions. I love the feel of it and my daughter sure appreciates the ability to build houses and towers out of the wood as well. The price is pretty steep but the quality of this product is quite high. I recommend this. I don't think I can go back to using plastic dominoes for this same purpose.
