A pity is that although I have ordered a large sound sphere with a diameter of 20mm, but received only a medium size. The diameter of the sent to me is only 17mm, although standing on the package that it is a big ball. So if you decide to buy it, should at receipt of goods may prefer again remeasure whether he gets what he paid.
In itself, this zirconia-ball sound is pretty - it is thickly covered with stones in two different colors, which also have a nice shine and the ball itself has a fairly bright sound. But in my opinion it not worthwhile to spend 40 euros for a glittering ball that loses its luster when it is in the space reserved for them followers. The money you can save - or rather invest in the normal, monochrome colored sound balls for 12 Euro. Pity!
