Absolutely terrible. Complete waste of time and money
Item was delivered and put together. The motion lasted around 15 seconds before stopping. After about using it 6 times it became completely tangled up and couldn't be untangled. I had no option but to throw it away. Complete waste of time and money.

Perfect gift!
Quality was great for the price, solid foundation so it continues to function well now. Size is great for popping on a desk .

Not for younger kids
The product itself is fine. But my 10 year old got the wires tangled within five minutes play… kind of thought this may happen, but not a kids toy as they just can’t help bashing the balls and making the wires tangle.

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.

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.
