LED Newton's Cradle, Newton's Laws with Swinging Balls, Physics Science Pendulum Balls Desk for Office Physics Teacher

Very poor quality. Cheap plastic. Light flashes on and off. After putting batteries in 2 of the wires came off. They are held on with a tiny bit of glue! Kept getting tied up which using and didn’t swing well before it broke. AVOID at all costs!!!!

This is such a let down. Its made of cheap tacky plastic..knotted string and the balls are different sizes. As soon as 1 ball clicks the other, it stops. The biggest waste of money.. the " light" is horrendous..2 settings ..off or flashing..a warning should come with it for those who suffer from epilipsy and headaches !

I went for the light up option rather than just plain metal balls as I think my daughter will prefer it and like the novelty of it.It does feel cheap. We’ve not tried to light it up yet as it’s a Christmas gift.Hopefully she’ll be impressed with the lights and being only 11 probably won’t care that it’s not great quality.It’s very light and plasticky.

Very pleased with the Cradle - arrived quickly and looks very solid and well-made. Much better quality than the one purchased previously [from a completely different seller] which had to be returned. It Is being played with constantly at the moment.

Didn't even try to see if the light up function worked, as the Newton's cradle doesn't work. The balls move for all of about 2 seconds before coming to a halt.

The media could not be loaded. This item is the worst possible quality. It simply isn't a newtons cradle, it's just plastic balls hanging between two bits of plastic. The light doesn't stay on and has a constant flash and overall its just rubbish.Even the box it arrived in looks like it's seen a lot of time thrown around a warehouse.Honestly, my little boy was so disappointed when it arrived. Just don't waste your money.

All twisted , unusable.

Product is very cheaply made and flimsy for the price, box and product damaged on receipt of item . Won’t be giving as a gift.

Le doy una estrella porque no se le.puede dar menos, una cochinada total las luces no dejan de parpadear una pelotita venia despegada y en si el aparato no funciona una porqueria total pero eso me pasa por comprar de rapido y no fijarme en las reseñas.

Lo descambio, no funciona, 2 toques y se para, no está alienado, mala calidad, luz si funciona pero necesita 4 pilas. Valen más las pilas que el producto.

Purtroppo il prodotto è arrivato danneggiato
