CERROPI Large Newtons Cradle Pendulum with 7 Balls, Physics Perpetual Motion Desk Toys for Office, Calm Down Fidgets, 50+ Sec Swingtime (Beech Base)

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!

It arrived in perfect condition and its just great ,looks good sitting on my sons desk , it was his birthday present

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.

Very nice. It seems a bit costly for a few of reason. 1: It just is; 2: it comes with and extra balls with not instruction on how to tie it in; 3: why do you need an extra ball? --can a ball break (there supposed to be steel)?; can a string break and a ball be lost? Some for me, some things are unclear, but it's a nice system that works well.

My husband loved this gift. He said it has a very attractive marble base with a lot of weight to it. It is made very well and does not look cheap. The balls swung with no issues, everything was balanced well. Great packaging with instructions. A great gift for anyone with an office setting. I included two photos that he sent me, I forgot to photograph it before he took them to work. As you can see it is a decent size with 7 shiny balls. You won't be disappointed.

My grandparents had one of these when I was a kid and now I'm able to share this one with my grandson. 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?

Really nice item. Well made.

I don't know how I even came across this, but my granddad had one of these sitting by his chair in the living room. It always fascinated me, so I had to get it. As luck would have it, my grandkids love it as well. I do have to keep it away from the 3yo since he manages to get all the strings tangled, but he will outgrow that.

la publicidad dice que la base esta fabricada de marmol G y pero es de madera, el tiempo de balanceo afirman que es de entre 50 y 60 seg pero son 20-30 Seg, por la información engañosa no recomiendo el producto, pero si quieres una base de madera y que el balanceo sea de 20-30 Seg lo recomiendo, los materiales metálicos son de buena calidad y las bolas están alineadas correctamente. no cuenta con las tuercas que se ven en la imagen en la base de los postes metálicos.

A quality product. Built for creating scientific curiosity (in my grandson😉). Should last for a good time. Performs as advertised.

As described, well packed & presented *****
