I am a professional bricklayer. I've had a lot of different grinders. This grinder is smaller and lighter, but just as powerful. It doesn't get hot, all other grinders have brushes, they get hot, it's brushless. I've only had it six or seven weeks. I use it almost every day, it's the best coffee grinder I've ever had. I've been using a meat grinder for 40 years. Runs very smoothly, I like the speed control. It has six numbers, from one to six, to set the speed, but you can set it anywhereβ¦
