Cats loved it.
This product was 'needed' for a lesson in physics in my homeschool. The kids enjoyed it, it demonstrated what it needed to demonstrate. On morning two, however, it was ridiculously tangled and I got annoyed with my kids (ages 14-9) because I had explained carefully to be easy with it. Untangled (which isnt great, but is doable). The next morning, however, my husband was the only one up, getting ready for work and heard this item clicking. The cat had discovered it, lounged out on the table beside it and figured out how to pull back the end ball and then proceeded to spend the next several minutes watching it swing until it needed to be reset. So, overall, this item pleased every member of our household, including the cat. The cat, however, did not take any responsibility for untangling the mess he made out of it.

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.

Twine used isnโt good quality or right for this device to work effectively
Theyโve used cheap twine material on this product that are way too thin and does not detangle well, ours turned into a tangled mess within minutes of opening it and it was impossible to detangle and get it to work!

The wires are so tiny once it gets tangled you're screwed, but it does what it's supposed to do

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.
