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.

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

Highly recommend!!!
Great price for this. Gave this as a graduation present. Material and size are perfect.

Lightweight and cheap
I returned this because it felt very lightweight and cheap. The balls are suspended using what looks like nylon fishing line. Not quite what I was expecting

Smaller than indicated.
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.
