Classic Newtons Cradle Balance Balls Science Psychology Puzzle Desk Fun Gadget (7 Ball White)

I work where small children are frequent visitors, and I try to keep something with a little motion on display as it seems to entertain them. This desk toy seemed 'just the right thing'. and I'm very pleased to have bought it. The metal part is very solid and well constructed, with all the joints firmly secured. The battery housing at the bottom is plastic, but the covers over the battery compartments fit well. The only thing I would change, if I could, would be to add an on/off switch to make it easier to turn the motion off. But the appeal of the toy overshadows the slight inconvenience of having to remove batteries. This is not a toy for children to play with, but if not within their reach I think they will enjoy just watching it swing to and fro. I recommend the toy, and the seller who has been very gracious about answering questions, etc. I will be buying other products from this vendor in future.

This is the cutest ever! Well made. It was a gift and was very well received! I highly recommend as a special gift or for a gift to yourself.

absolutely my favorites perpetual motion toy I own, and I own a lot

There is a gap between balls... NOT precisely made.

It works.. but, not great.The send to be too much of a gap between the balls and it looses it's momentum after just a couple of swings.I have used others and they bounce much longer.For the price I expected much better quality.I think the flexible frame also contributes to the quick momentum loss.

Great weight to the spheres and metal frame, but the line came detached from the frame so that one of our spheres is hanging loose from the others. It’s not possible to repair as the holes where the line attaches are sealed with what looks like hot glue. We like the item, but it’s disappointing that it broke right out of the box and is not clear how to repair it.

Box it came in was thrashed kinda confusing what batteries to use but it works great and looks cool. L

cheap but nice
