I love the wood aesthetic. It's a pretty knick knack to have around. It's a little pricey, but after reading reviews of cheaper ones I decided to go with more expensive. It's definitely worth paying more for good quality. What I didn't appreciate was getting an email about infant sleep safety as a result of this purchase. Just because the product name has the word 'cradle' in it, does not make it an infants sleeping place. Can we do away with the AI purchase police? Review: Attractive, very well built. Great way to demonstrate kinetic energy - Excellent quality and packaging protected it. I bought this for the conceptual Physics class in our home school curriculum. The kids love it.
