Review: Made with care. Packaged with care. Delivered with care. - Made with care. Packaged with care. Delivered with care. This is solid quality. It’s heavy and feels durable. Shipping was fast and is worth every penny spent. It was very easy to take out even though it was packaged very carefully with each ball in its own compartment and wrapped. It even came with an extra ball and string. Although it came with instructions, I was too excited to read, its easy enough that you can get it out and going without needing the instructions. I took my time and was careful not to twist or tangle anything. I don’t see this as a toy or something for small kids to play with as the strings are delicate and can get tangled if not treated with care. It looks good on my desk at work and from time to time I get it moving. It doesn’t last very long, but the sound is soothing. Spend the money and get it!
Review: Looks nice. - Very nice. Gave to my kid for Christmas and he loves it.

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.
