I cannot remember ever buying a grinder that was as much a piece of junk as the Black and Decker CBM 210C.
Positive Product Points
Seriously, I would like to say there are none because no matter how solid the build of a product is, which this product is, if it does not do the job intended then there is nothing I can say that is positive.
Negative Product Points
Finest grind available is a coarse grind with bits of broken bean. No matter how one tries to adjust the burr gap, you get coffee suitable for an ancient aluminum percolator or the camp fire tin can.
I purchase an inexpensive burr grinder and Bodum cafetierre, every so often, to take with me on business trips - hotel coffee being an abomination. I have owned, over the years, a Philips, another B&D, and two Brauns. They all wear out eventually but they are light and extremely portable. The Philips was by far the best but the burrs wore out and it is a discontinued product. The need for a grinder once again arose so I visited the stores that would carry a fifty buck burr grinder and they only product I found was the Black and Decker CBM 210C.
When I first tried at fine grind (I use fine grind in my Bodum - there is trick that works and gives Turkish like texture), the grind was in chunks like the beans were hit lightly with a meat cleaver. After serveral attempts to adjust the burr gap, I received a peroclator too coarse for even a traditional Bodum grind. If you are going to use a drip method, I recommend you forget it. It would impossible to get a filter grind.
This product, simply put, does not deliver. It goes back to the store I bought it from. My true rating is a goose egg, zero, nada. It is not even worthy of a one.
What can I say, I purchased it at WalMart. Polite courteous cashiers with a generous return policy (thank God).
