Bests & Worsts Reviews from Amazon

I don't know about the other reviewers. I can get a cup of flour in a much shorter time that 10-15 minutes. ?? That being said it is a MANUAL grinder. I use my electric when I want a lot of flour. I basically got this one to crack grain for cereal, but then we found out my daughter has non-celiac gluten intolerance. This is great because I was able to take this apart and wash with soap and water and dry really well, so we are able to grind rice and other grains without it becoming contaminated with the wheat. I use my electric grinder to grind up my wheat and now this one for other flours. It is manual, so it is hard work if you are grinding up large amounts of anything. For that I recommend an electric model. But for small amounts or for a preparedness tool, this is a great grinder. One last note: Although my flour from my electric grinder is a finer flour than I can get out of this grinder, this grinder still grinds flour fine enough for bread.
