Disappointed with Quality
Reviewed By: LAllen (Charleston, SC)
The quality of the steel balls is less than ideal for a Newton's Cradle. The balls don't transfer the momentum efficiently and all 5 balls end up moving after the 1st collision. This eventually happens with any Newton's Cradle, but to have start so soon was a big disappointment. I've seen much better. My guess is that a lower quality steel (one that is too soft) was used to keep the price reasonable. I would recommend looking elsewhere for a better quality product.

Just as I remembered it - from the 70's. Well made and well priced.
