Query: this grinder sucks.

Okay, this is the first time i've written a review, but I had to because I'm usually very easy to please. NOT this time! This grinder (for $[...]) is awful. First of all, the SECOND time i used it, the grinder was running, yet the beans wouldn't go down into the grinder and it just whizzed away (which by the way, will throw off your cups measured if it thinks it's grinding and it's not). I had to knock on it just to get the beans to grind. THEN, the even on the coarsest setting, the ground coffee was WAY too fine. Just like baby powder. It made horrible coffee that was very bitter. And don't say it's my coffee maker. It's not. Very dissapointed.
