A very good desk toy, albeit bought for a boy who really enjoys watching and hearing it work.

Ideal for an 8y rold

When I got money problems

Seamless art of beauty!

I had bought this for my granddaughter as she is interested in science. While this item arrived well packaged, it was incomplete, with the base and one of the balls missing. The rest of the balls had either snapped off their nylon wire or the attachment had snapped off. Totally unusable and it has been returned.

Bought this as a Santa gift for our daughter who loves all things science. It feels like a good quality product, nice weight, good materials etc. However, the balls stop swinging after a very short time. We think that on this particular one, the strings on one side were glued onto an incorrectly positioned pole. The poles should mirror each other and they do not. Because of this, the strings aren’t straight, causing them to hit only a few times before stopping. We have ensured that we have assembled the item correctly (fitting the bars into the base) and we had someone else check this out for us also. It’s very unfortunate because the Newton’s Cradle she uses at the local library swings for quite a long time.

My husband tells me he has always wanted one. I didn't know this!. So i ordered it. When i gave it to him, he was delighted!. Everytime we are near it, we start it off !. Easy to assemble too.

The product looks good and came well packaged in my case. It was easy to assemble, but for a 'perpetual motion' device, I was rather disappointed as it only works a few times then they all just swing too and fro at the same time. Not how I remember these things working. I couldn't pinpoint exactly why it doesn't behave as it should, so I don't set it off ever anymore, it just sits there, not working....

Stabile, nessun difetto, lo avevo già comprato e fa il suo effetto soprattutto se una scrivania a contatto col pubblivo

Kul men kort

Ein interessantes und sehr schön verarbeitetes Pendel, das als kleines Ausstattungsdetail oft zum kurzen „in Gang setzen bzw. spielen“ anregt. Sieht gut aus und die Pendelaktivität fasziniert immer wieder.

Muy bonito, funciona perfectamente y después de casi un año sigue como nuevo. Llegó rápido y en perfectas condiciones.

Parfait reçu de manière impeccable pas de nœud, bonne tenue
