This is defiantly a good burr grinder for it's given price. The MDF has a large range of grind settings, from 1-32, which allows it to be used from several coffee makers (espresso, drip, french press, etc.).
Negative Product Points
The doser is not state of the art. When adding ground coffee back, it leaks slightly, and is difficult to dispense. It also doesn't get all of the coffee out. Recently I spent a while cleaning it, which produced a lot of coffee hidden in the back that the doser didn't dispense.
Detailed Commentary
I would buy this grinder again, but if I had enough money I'd go with the rocky. The grinder works fabulously, very constant grind, but the doser turns me off. The main difficultly I have with it is attempting to put extra ground coffee back, which always ends up with it spilt onto the table. I tend to also find coffee stuck in various nooks of the machine, which irritates me slightly. I suggest that every time you finish with the coffee beans, turn the machine upside down and dose until no more extra coffee comes out.
Buying Experience
It took a little longer than originally said, but besides that, essentialespresso.com was very corporative.
