An utterly useless product. You would get better results grinding your beans by hand with a mortar and pestle. I’m not sure why a respected company would risk its credibility by coming out with an inferior “grinder” like this. I know this is not an Infinity grinder, and costs under $50, but I expect it to grind coffee beans. I must say, while it sits on your kitchen counter it does have the appearance of a professional grinder, so it will impress your friends. The ground result of its somewhat promising noise-making will, however, be unusable for anything but mulch for your garden.
