Relatively expensive and unable to produce a fine grind.
Positive Product Points
Looks and build quality
Negative Product Points
Coarseness of grinds, difficulty of cleaning, amount of ground build-up in machine.
There are quite a few bad points- enough that I just returned it to where I purchased it. The grind is very coarse. Even after taking the front piece off and manually adjusting the burr grinders to their minimum clearance it wouldn't produce anything finer than a fine drip grind. Nowhere close to, to take a specific examply, Illy preground espresso. So that's point one (and a big one). The machine is also rather poorly designed for coffee throughput. There are multiple ledges above the vertical throat on which beans can, and do, sit. Whole beans can and do get lodged within the inner workings. Ground beans also accumulate within the workings. It's difficult and messy to clean all the old grinds out when switching coffees.After removing the glass catch basket extra grinds will always fall out onto the machine base. The glass catch basket is not solidly attached in any way and it is very easy to knock it off the base. I am certain it would have eventually been broken had I kept the unit. The final negative point is that the coffee I brewed with it was "good" but when I went out and bought a different brand (Solis Maestro) the results improved dramatically due to the uniformity and fineness of the grind.
As a point of reference, I'm a mechanical engineer and have no problem with mechanisms. I'm very confident, after having pulled the unit apart and then put it back together, that the results I got couldn't be improved upon with the unit I had. It's conceivable that this was a "lemon" but I wasn't interested in finding out by getting a different unit.
Buying from Williams Sonoma is always a pleasure. They are completely accommodating and took back the grind without a question.
