This replaces an electric coffee grinder, which was rather loud. Our options were to grind our coffee the night before or hope the noise wasn't too disturbing. This coffee grinder is the answer to my problem. It is easy to use- just add your coffee beans to the chamber and grind to the desired courseness. I love that I can grind it a little less for use in my Coffee Press by adjusting a nut. Clean up is easy, too, as it can be taken apart. No need to wash, just use the included brush for any pieces that are left behind. #rankboosterreview #sponsered #Firlar
