This is the first "good" grinder I have owned, after using a cheap whirlyblade grinder for many years. The difference, both in terms of ease of use and quality of results, is pretty dramatic.
The most important thing about a grinder is, of course, the grind. And when it comes to a consistent grind, this machine delivers. I have spread the ground coffee out in my hand and it is very uniform. Furthermore, it's hard to imagine someone needing a finer grind than this machine is capable of. I use a Krups Moma Brew (a pressure brewere, albeit not very high pressure), and my standard setting (after experimentation) is actually towards the coarse side of the range. Unfortunately, I can't comment on the consistency of the grind at the finest setting, as I personally have no need for it.
This grinder is also very easy to use and live with. It runs fairly quietly, particularly with the lid on - I'd say about as loud as a typical microwave. The bin and hopper are very large and could handle any non-commercial load of coffee without trouble. The static level is very low, despite the dry climate I'm grinding in. Also, the machine looks sharp on my counter.
About the only negative point I can think of is that this machine leaves a noticeable amount of coffee grounds in its gears. Probably not more than a half-teaspoon, but it's enough that if you change beans from one day to the next, you will notice the splash of off-color beans coming out first in the next grind. The machine is very easy to take apart, and the included brush can easily clear the gears, so if you want, you can completely grind every batch with a little extra effort. For those who are fanatics about getting their measurements just right, this may be a useful step. For me, it's no more than an aesthetic problem, and it's not worth an extra 20 seconds every morning to solve.
I have the brushed metal model, which is more expensive, but feels nice and solid and fits our kitchen decor well. The plastic-bodied version looks like a fantastic value.
