Query: Disappointing.

I'm very disappointed in this product. I was looking for a coffe grinder that would give a more consistent grind than the blade grinders I have tried. My experience with this grinder is that it is no more consistent than a blade grinder. I get everything from powdered coffee to the grind I selected. Not only is the grind consistency very poor, it runs at a very high rpm and is extremely noisy. It is louder than my blade grinders. If you're into a lot of noise and varied grind sizes in your coffee, then this is you're grinder. If you want something that doesn't sound like you're sanding hardwood floors and actually gives a consistent grind then keep looking.
