No manual on/off switch Not enough grind settings to "dial in" Odd shaped grounds chamber One bean gets stuck every time!
This grinder is a great step-up from either whirlyblade or lesser-quality burr grinders. I bought the brushed SS model. I'm not sure I would have cared as much for the model housed in black plastic - the additional weight of the metal housing gives this grinder the added stability that it needs. I use mine for manual drip and FP coffee and I've been pleased, although I've heard it does an admirable job with espresso grinds.
The low static of this grinder makes operating and cleaning it that much easier. I find that the grounds chamber is unnecessarily odd shaped - a very minor flaw. This grinder has no manual on/off switch, which I find is its major drawback. It runs on a wind-up timer, and to turn it off prematurely, you must turn the entire grinding hopper counterclockwise to the "no grind" position. I think that some will find that this grinder has too few grind settings.
I will probably continue to use this grinder when I make the jump to espresso, although I see a Rocky in my future!
Bought from Cafemaison.com with absolutely no problems. Excellent customer service; a very positive buying experience.
