ABOUT CERROPI We're a family-run business who specialize solely in manufacturing Newton's Cradles. We've been selling online for 11 years, and are committed to excellence in both manufacturing and customer service. Review: Very Impressed & Definitely Recommend - After reading reviews of other Newton’s Cradles, it seems like a common problem is that the balls don’t swing back & forth for very long. This cradle however, does not have that problem, as it goes for about a minute & a half with one release. I’m guessing the 7-balls (vs most cradle’s 5 balls) makes a difference. We got the wood base model and are very pleased with it’s sturdy quality and it’s simple but attractive look. Take note, do not release the first ball from too high otherwise the balls/strings can get tangled, which can very easily and quickly dissolve into a knotted mess. Fortunately, the customer service at CERROPI is proving to be fantastic bc my son did, indeed, release from too high and the balls got tangled. CERROPI support immediately responded and tried to help me fix it myself but then quickly offered a replacement (I wouldn’t recommend counting-on the same outcome if your balls/strings get tangled). As someone who feels like decent, let alone fantastic customer support is a very rare thing these days, I am very pleased and grateful for the response I got from CERROPI. I would DEFINITELY recommend this Newton’s Cradle for anyone looking for one. I was hesitant to spend a little more bc there are definitely less-expensive ones out there, but I doubt the quality is nearly as good with the cheaper ones, and I’m very glad I spent the extra money to get this high-quality cradle, not a cheap, plastic one.

No rust **Q: What is the length? The title states 11" while the product descriptions specifies 9".** A: The length of the marble base is 9.06 inches, the width is 6.69 inches, and the diagonal length of the marble base is about 11 inches. **Q: we had one before from a mall and the balls were tangled so we couldn't use it does this one have the balls where they don't tangle ?** A: The one I ordered through Amazon was packaged very carefully with each ball and string wrapped in plastic. The strings were not tangled. The unit has not tangled; the balls are heavy weight and seem to be good quality. I am sorry that you had that experience. I enjoy the cradle so much; it is intriguing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very Impressed & Definitely Recommend *by S***. on 17 February 2022* After reading reviews of other Newton’s Cradles, it seems like a common problem is that the balls don’t swing back & forth for very long.
