Great science learning
Very nice but beware of tangling nylon cords if used with too young of child. I recommend this for 8 yr old and up.

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.

It's Hypnotizing
I've always wanted on of these. Now in my second childhood, I got one. Now I can't ever pass it by without setting it motion. You can spend hours thinking about the physics of motion that is going on here. Good brain workout.,

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

Decorative, relaxing, and well-built
This 7-ball Newton’s Cradle is a great desk decoration and surprisingly fun to watch. The balls are well-aligned and the motion is smooth, clearly demonstrating the physics principles in a calming way. I keep it on my office desk, and it always draws attention. The clicking sound is soft and not distracting, making it perfect for a work or study environment. The base is stable and setup was very easy. A great gift for science lovers or anyone looking for a unique desk accessory. Very happy with this purchase.

The item delivered was much smaller than indicated, the base was only 9cm x 8,5cm and the height was only 9cm. The principle of conservation of momentum was demonstrable and so will be adequate for its purpose. However I was disappointed with the size. This needs to be amended in the product description.
