Came smartly packed to ensure no tangled knots! Very fun for the kids to play with!

It’s inexpensive for a reason. It’s flimsy and you don’t get the full effect if you pull back more than two orbs because the strings are too light. The orbs just bounce all over the place rather than in the expected direction. It runs out of kinetic energy after about two to three seconds. It’s not fun to watch. It’s more disappointing than anything. I teach middle school science and I was hoping this would be a nice way of demonstrating Newton’s laws of motion. I would not recommend. Spend a little more on a better rated product and you won’t regret it.

Gift for friend. She likes it

Not the best newton's cradle but if you're looking for something inexpensive for your desk, it is ok. Has gotten tangled a few times and then it doesn't work as well once it has been untangled. The strings become kinked. Not the most durable.

this one was very fun, but it gets tangled too easily

I got this as a gift for my friend and he really loves it. The quality is pretty good for the price. It’s a good stress reliever to have on your work desk.

It works prefect and I love the packaging so that I can put it safely in the box when not in use. I used it for teaching the law of cause and effect. I have seen others that get tangled up and are hard to move from place to place. this is perfect and compact and stores nicely for travel.

It was nice looking but didn't bounce for very long. maybe like 20 seconds. not near as long as it should.

Just what I ordered and gave as a gift.

Delivered after 1 Month

Good product, good service,

I returned this item because the base was scratched, and not the colour ordered. It was also half the size of the dimensions listed.

Very small, doesn’t work properly. Cheaply made
