Excellent quality but very light,
Verified Purchase(What is this?)
This review is from: Zeon Newton's Cradle Executive Desktop Toy (Kitchen & Home)
This product looks and feels "executive", everything seems to be made of good quality materials.
However the base itself is very light and slippery. So if you keep this on an office desk and move the steel balls they shake the whole toy and reduce the time it operates, I've solved the problem by sticking blue tack at it's base but it's something the manufacturer should have taken into account.
