OK grinder for drip, vacpot, presspot, but forget it for espresso or finer grinds.
Positive Product Points
Cheap and ok if you don't need a fine grind.
Negative Product Points
Unprecise Noisy Builds up lots of static Not enough range for espresso Clogs constantly with oily beans.
I got this grinder as a present so I gave it a good chance, and if you are not going to be using it for espresso and other types of coffee that needs a fine grind, it will do ok. Forget about a late night cup, you will wake up the rest of the house.
As soon as you try to use it for espresso grinds, that's where the problems start.
It's unprecise, dial it in at 3 for some dry light roasted beans, then 4 for some oily darker beans, then back to 3 and it's way off, I wasted to many shots because I choked my pavoni. Every time you use some different beans you end up wasting a shot or two to get it dialed back in, you can't just write down what grind setting you used last time as it will be off. I guess this is not such a big problem if you stick with one type of beans, but if you home roast and/or like to try lots of different beans, it's frustrating.
When using oily beans, I sometimes had to take of the doser box 2-3 times to un-clog it to get enough for a double espresso, this is extremely annoying.
It has a very limited range for espresso, 2-3 steps on the adjustment ring at best, and each step is to coarse so you have to fiddle with tamping pressure to get your shot timed right.
After grinding you have to bang the sides of the doser box and flip the lid slowly, or the static discharge will blow grinds all over the place.
As I got it as a present I can't realy say anything here.
