Good Item
Good item. Just what my 8 y.o, grandson wanted. He’s happy so I’m happy.

Its physics.
It goes click clack...does what its meant to and the stand is flat so no issues. Theres no way to gussy a newton's cradles up. Its basic physics and honestly whole some find it annoying I find it relaxing. It also confused my dog for about an hour. Scared the cat tho lol

Very good toy or fun ornament
It's ok for the price. Not high precision but good enough as a child's/teenager's toy or for general fun use. I didn't have any packaging problems: it was very well packed and everything was held in place by solid foam blocks, with no chance of the wires becoming entangled or anything, if unpacked sensibly.

Great science learning
Very nice but beware of tangling nylon cords if used with too young of child. I recommend this for 8 yr old and up.

Genial
Tener un péndulo de Newton era un deseo de mi hijo, y estas navidades ha sido la ocasión perfecta. Había muchos modelos a elegir, y todos tenían algunas malas críticas que nos hicieron dudar en cual coger. Pero éste, ha sido todo un acierto. No es que dure mucho rato el movimiento ,pero a los padres, ya nos va bien que así sea..
