Customers say
Customers find the Newton’s Cradle visually appealing and worth the price. However, the build quality receives negative feedback, with customers noting it’s made of cheap plastics and the base is flimsy. Moreover, the motion retention is poor as it never stays in motion very long, and the strings get tangled together quickly. Additionally, the functionality is mixed, with some saying it works excellently while others report it only works for 10 seconds.

Physics is cool
The balls will occasionally tangle if you make them go too fast or lift the end one too high but Iâve untangled them multiple times from kids playing with it and it still works as expected. The frame is very light and plasticy but the balls do what theyâre supposed to do.

Donât buy it
Terrible! Bought this for my sonâs birthday and when we assembled it, it didnât work and broke within minutes. I bought it early so the return window closed. Waste of money, do not buy it!

Great untilâ¦
I had this in my classroom and it was perfect until it accidentally got tangled. It quickly became a jumbled up mess and had to be thrown away. ð

Perfect gift
I gave this to my boss and he loved it.Definitely a great birthday gift for someone in the office.

Not bad, but…
The little marbles do not line up perfectly straight, so the effect of their moving together doesn’t always work. Next time I would get a slightly more expensive unit.

Great quality for the cost
My son has been wanting one of these for so long. He has been gifted ones that have had thin plastic strings that broke almost immediately but this one was packed well, strung well, feels of good quality and it’s lasted multiple days of constant use by my 10 year. This is a great buy for my family.

Itâs a great product!
It would have been great if it wasnât broken upon arrival. When I tried to get another one the system wouldnât allow it so I had to do a full return. Disappointed that it was broken.
