I have one of
these cuisinart things and it's been working fine for several years. Not great reviews on Amazon, but I think some of those reviewers have pretty high expectations for a $40 burr grinder. I find that it does not create a perfect grind and would not be great for a high end espresso maker but does great for drip coffee makers on a medium grind. There is a little dust created in the grinding process, so when you french press with it there is some fine dust that gets through the screen and makes a small amount of sludge at the bottom of the cup.
