## Customer Reviews

### ⭐ 







  
  
    Not a functioning model
  

*by C***S on Reviewed in the United States on June 29, 2018*

Very disappointed not a classic newton cradle. It is aminiature reproduction that swings for 10 seconds. The balls are smaller than marbles. Buyer beware. Cheap plastic base thin fishing line for string. Not nice.

    BE CAREFUL !
  

*by M***S on Reviewed in the United States on September 18, 2018*

had to buy 2 because someone knocked the first one on the floor and was sooo tangled ,the only thing to do was get another! Just make sure you put it somewhere safe and always store it or transport it with all the packaging it comes with.

    Don’t buy it
  

*by G***T on Reviewed in the United States on January 8, 2019*

What a piece of crap.  So disappointed.  Doesn’t swing very long.  Took to work still packed and I was embarrassed when my co workers tried it.  Going in the trash
