Nice
Always loved these. This one lasted about 3 weeks but not because the product is flawed, because our son was very rough with it and got it twisted up. The product itself is just fine.

Great teaching tool for classroom
This Newton's Cradle was a great teaching tool—my students grasped the concept more easily. Monitor use as the strings can tangle. It arrived promptly and was perfectly packaged.

Works as expected.
This cradle is small-ish but arrived packaged well and works as expected. Perfect for desk or table. The wood base gives it a nice look. I am happy with it for the price.

Not great
Worked okay for a few minutes but broke way too easily. Barely even did anything and one of the balls just snapped out. The string they are on is not very secure. It looks nice but didn't last long

Relaxing item
It's smaller then I thought it would be but still looks and works great.
