Okay product

My kids love it but it doesn’t last as long as others and one of the balls snapped off after they accidentally got it tangled(which is surprisingly easy to do)

Waste of money

This Newton's cradle only bounces back and forth 5 times. My daughter and I were quite disappointed. Just feeling the balls weight you can tell that they are hollow. Only solid balls on longer strings will give the 30 seconds of action time that a Newtons Cradle should provide.
