BOJIN Newton's Cradle Balance Ball Science Puzzle Desk Mirror Toy - Medium

This newtons cradle looks really nice and appears to be well built but it just doesn't work like a newtons cradle should. As a previous reviewer wrote it only bounces about 6 times (in my experience even less) before you have to start it over. I'll be returning mine and looking for something that actually works.

Balls were not aligned after setting up. Improper alignment doesn't allow energy transfer and makes this device useless.Bought this for my nine year old daughter for Christmas and she was obviously disappointed. Will be looking to return tomorrow.

Smaller than I expected but my son really likes it!

So not worth the price...box says motion should be at least 15 seconds. The one I received is not even close...more like 1-3 seconds. Not a good example for my Science students. Boo!

My students love this.

Had to return because the strings weren't installed right and would not swing properly. Cheaply made.

Terrible....absolutely terrible. It bounces maybe twice and loses momentum in less than 20 seconds.

Amazing product.
