Review: Great choice - I love a great Newton’s Cradle for myself. Very relaxing to watch. I purchased this one for my autistic. It was very nice. The second one I’ve gotten for him and the second one he has tangled up and made completely unusable within ten minutes. Not this company’s fault. The unit itself is a great quality. It’s a good size for an office desk or any display area. The magnetic balls have great weight to them. The plastic strings as mentioned, got tangled easy, but not because of the craftsmanship of the item. It’s a user issues. All in all. It’s a great choice.
