Surprisingly my wife wanted a new bench grinder for Christmas. Our old Sears mill got to the point where we had to start it manually. I was surprised by the poor reviews of most grinders on the market. The price of the Metabo coffee grinder was much higher than others, but the reviewers said the quality is better day and night. That is indeed my experience. This is a true commercial, high quality, heavy duty (heavy emphasis) product. Runs smoothly and almost vibration-free. In fact, I haven't even bothered to screw it to the bank until now. With this device, sharpening shovels and axes is a real pleasure. It's too early to tell, but I suspect this device will last a lifetime.
