Inexpensive, seems solid, stays put while grinding (for me at least), not as loud as my blade grinder, looks nice, larger capacity than blade grinder
Negative Product Points
Very poor grind for drip -- as bad or worse than the blade grinder I got this to replace. Burr material -- is that plastic in there? Very dull whatever it is. Static is a big problem.
I've had a blade grinder for a long time, since "it's better freshly ground". But I always found it was better preground, fresh out of the bag. I eventually realized that the grind quality of the blade grinder was at fault and could be improved upon by getting a "burr grinder". Got this one after reading some reviews (amazon maybe?). I was expecting to be impressed, but couldn't shake the feeling that this might have been no improvement. I tried all the finer grind settings, none of which is very fine. In my melitta cone, water pours through even the finest grind from this grinder in maybe 20-30 seconds. Comparing that with the 2-3 minutes preground gives, I saw where the problem was. To get a decent cup I use tons of coffee ground on the finest setting, and it's barely passable.
A closer look shows two things. One, the grind is a mix of a wide range of sizes. There's lots of fine dust that gets stuck in the corner of the bin (as noted by other reviewers). Even if you dump this you still have a lot of very fine particles. Why doesn't that cause the water to back up instead of running through immediately? I think that what happens is that the dust takes a while to get drawn into the bottom of the grounds. Before it does, my cup is full. But if you brew two or three cups worth, you see it: the drip slows dramatically. I guess that's the dust finally clogging things up. So you get the worst of both worlds this way.
Two, if you take the hopper off to look at the burrs to see how this could be happening, you see that the grind adjustment system -- just the hopper threading into the base -- allows the "stationary" burr (screwed to the hopper) to wobble. That, and the burrs seem to be made from plastic! I haven't taken them out to verify, but they seem very light -- and in any case, very mild and dull.
I've noticed many reviews of this say things like "not good for espresso, but it should be fine for drip or press..." without actually testing it on drip or press. It's really not fine for drip, for me at least! It's a waste of coffee! More than negates the benefit of buying whole bean. I haven't tried it for press, or for espresso, or Turkish for that matter, and have nothing to say about its performance in those applications.
