It’s very cool to watch and it takes a long time once you get them started for them to finish

The whole family loved it! The grandchildren and their friends would play with for hours, and you don't need batteries!

Nice

I was thinking this was the type of Newtons cradle that swing’s knocking the other side out and continues on. I find this version to be more interesting and you don’t have to worry about the clicking noise because these never hit each other. It comes mostly put together in the box. It comes with some white gloves to keep it from getting fingerprints while putting it together and a cleaning cloth for later. A ruler that’s also included must be used to get the desired effects. While I think that it’s a neat table top item there’s really not a whole lot to it. If they wanted to sell more I feel like the price should be $10 cheaper. It has more balls than the other style cradle but it’s really just basic components. My kids and I enjoy this and from what I see there’s many more of the other styles than these making it a little more unique. I have no reason not to recommend this although I feel like it’s a little overpriced.

This Is fun but be careful of the string.

I have to agree with the reviewer that wrote: "This is too expensive for the dimensions to be off as much as they are. It works in the loosest sense. People who don’t know how it’s supposed to work will like it, but if you want to visualize clean waveforms, this is not the one." Therefore, I cannot recommend this to anyone in good conscience.

Expertly crafted. Expertly packaged. Expertly delivered.Shipping was fast, and every penny spent feels worth it.Each ball sits securely in its own separate compartment. Removing them requires a gentle touch to avoid tangling the strings, but with a little care, it’s easy to manage. The set also comes with instructions and a ruler to help set it in motion. After firmly securing the stand to the wooden base, use the ruler to align all the balls in a straight line, pull them out to an equal distance, then release the ruler—and the motion begins. It’s not just balls hitting each other; they swing in smooth, curved patterns, like a wave.I took my time assembling it. The stainless-steel stand snaps into the holes in the wooden base with a bit of pressure—just make sure it’s fully seated so the base stays solid. I was careful not to bend or tangle anything along the way. Once properly set up, it works perfectly. It looks great on my desk, and I find myself playing with it now and then. This is built to last.

Not worth the money. Steel frame inserts into holes in too thin wood base and wobbles when balls are swinging. Poorly engineered, needs diagonal bracing and heavier base.
