Hardly bounces
The balls look like metal, but they are plastic and hardly bounce.

Should have listened to the reviews
My boyfriend wanted one of these but when he went to try it they only clicked about 3 times. We thought it would make a good piece to just sort of show off instead, but this morning I came downstairs and it's somehow all tangled and a string has broke off one of the balls. Was there an earthquake last night here in Michigan? Oh, don't regard the incense ashes to the side..

Does not work as intended
I purchased this product for my husband’s office. Although it arrived packaged well, the product does not work as intended. It is very disappointing, especially because I selected this one over the others because of the great reviews. The balls do not knock back and forth more than two or three times. I will be returning this and buying a different one.

Really a waste of money - get a different model
Have bought Newton's Cradles for years as a gift to my physics students. This one only lasts 3 or 4 swings before the momentum dies out. Really a waste of money - get a different model.

Tangled and worthless!
Product arrived, but it was unusable. Everything was tangled up and it was impossible to fix. Also, one of the strings was not attached to the edge. Horrible experience!! I want my money back or a replacement!

Horrible quality. Cradle worked for three seconds then stopped
Horrible quality. Cradle worked for three seconds then stopped. I’m using work in the lightest sense of the word. Returned it.
