I like using my Coffee Grinder. All you need is a little elbow grease and it grinds those coffee beans down finely. You can also adjust it but I prefer to use it to make it the finest so the water flows through the Keurig Cups. It is not hard to use. I usually fill it up half way and that makes about 2 cups off coffee depending on the size cups.
It is made from high quality stainless steel and is easy to clean. I have had a bag of coffee beans for over a month and did not have a grinder. This comes in so handy and the taste of fresh grinded beans makes coffee taste great. I prefer now to grind my coffee then to buy it canned or Keurig cups. It is also great to take with you because it is not big. You can make your own fresh coffee when on a trip. So much better than instant. It is easy to adjust and take apart to clean. I received this coffee grinder complimentary in exchange for my unbiased review and opinion. All opinions and words are my own.
