LED Light Up Newton Cradle Balance Balls Newton Swing Glass Ball Science Psychology Puzzle Desk Fun Toy for Office Home Decoration (D)

Very poor device.Flimsy, plastic and doesn't work. The plastic balls aren't even heavy enough to pull the nylon threads straight, so they don't swing properly and will stop within a very few seconds.

Very good Christmas present.

This product came broken and it’s cheap and flimsy. The pictures look like a really good gift. I bought this for my nephew however the newtons cradle is not like the pictures atall. I’m actually really upset with the product and would appreciate a full refund.

Arrived in good time.Alittle flimsy than expected but nice looking all the same.Unfortunately will be returning as arrived with a ball unattached I can probably try and glue it but shouldn't have to really.

Very disappointing. Cheap, plastic and not how pictured. The lights flash rather than staying on. The motion lacks energy to be perpetual. Total waste of money and effort.

Cheap quality. Doesn’t work as it should but it does light up

Cradle itself is quite lightweight, comes carefully packaged and is novel. The only thing I would say which isn’t a massive issue is the lights flash rather than being static.

No concerns
