Does what it says on the tin!
My wife finds it very relaxing! Would like it to cradle longer myself but it is quite small which is as advertised.

Not great quality
Very poor quality and much more plasticky than it looks in the picture. The packaging was very damaged although the parcel it came in was not so I suspect it may have been returned at least once. It was supposed to be a gift

Fair quality for the price
There were no instructions for how to put together, fortunately my husband is useful some of the time. Fair price for the quality, it was what I expected. Brilliant delivery time

The cords get tangled very easily, and I couldn’t disentangle them. Waste of time and money.
Had a problem because the instructions to keep the box flat were inside the box, and so the cords were twisted as I had been holding the box upright to withdraw the balance balls. Would have been no difficulty if the instructions were visible on the outside of the box. Take care!

Not sturdy enough
Definitely value for money however you get what you pay for…..it looks good from afar but it is very lightweight so not sturdy and up close it is cheap looking.

Broken before assembly.
The cradle came with the middle ball already chipped off the wire, literally 10 minutes after I got it delivered. 1/5 stars, appalling quality for the price.

Pendel funktioniert gut, was auch an der Größe liegt. Der Aufbau ist gerade und fest. Als Spielzeug für Schulkinder geeignet. Aber auch ideal nutzbar, um Impulsübertragung und Kraftstoß zu demonstrieren für Jugendliche und Erwachsene. Preis-Leistung ist sehr gut.
