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.

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.
