So I had heard some disconcerting reviews about some things pertaining to this mill. None of them were valid criticisms for the one I received. Assembly was easy. Mine came with an on off switch. There are some things that you do have to pay attention to like proper alignment of the mill stones. I did cut a gasket to fit around the Millstone cover plate. I noticed mine did have a little bit of a gap so I tried a thin slice of Teflon, one of those cutting boards and that was too thin so I took a Keurig coffee pod box flatten it out Cut a circle with a 7 1/16 ID and about a quarter inch wide and sandwiched in between the spinning stone and the cover plate and it worked perfect. There’s no flour dust flying out of mine. I’ve used it several times. It worked great. I love mine. April 9th, 2024
