Mini Newton's Cradle Balance Balls Desk Set - Art in Motion (5 Stainless Steel Pendulum Balls, 3 1/2-Inch Frame)

For the price it works great.

This "newtons cradle" is low quality, broken when I got it, does not do what it is supposed to do, and its balls are not even at all. It is a HUGE waste of your money and time and I really regret buying it. Please do not buy it unless you want to be disappointed.

The item was delivered broken. I still enjoy having the item

Not bad for the price but it feels kind of cheap; the balls don't precisely line up so it loses momentum very quickly compared to higher quality sets.

I opened the box and easily put it together but after a few uses it has 3 of the 10 strings broken on 3 different balls. I tried to put them back on and one worked.

I was nervous when I read plastic but it is sturdy and the balls are heavy. My son plays with it everyday.

Exactly as expected!

It came broken, and only works half the time. Not worth it.
