Let me be blunt about this product.
A little upsetting that the balls don't chime correctly, it sounds like a rock tumbling in it instead; but other than that it is a good size for my hands and feels good when I roll it. Another complaint is that the ones I got looked used and I felt like the seller just shipped me ones that they were trying to get rid of hoping that they could trick a blind person or something? Even a blind person would know these balls are low quality.
