Small, fast to use, very easy to clean. Good results for drip coffee and vacuum pot (cloth filter)
Negative Product Points
Not adequate for espresso. Also burr grinders will give better results for French Press and for Moka pots.
This little blade grinder is perfectly adequate for drip (paper filter) and vacuum coffee (cloth filter) and even for French Press. For moka the coffee tends to taste weak and in the press pot there can be too much dust in the bottom of the cup if you're not careful.
In my experience it isn't adequate for espresso not even with a PPF.
But for drip and vacuum pot it works fine and it is faster than manual burr grinders. Also it is less messy and easier to clean than an electrical burr mill (and cheaper too) while the final brew won't be much different (I am talking of low end burr grinders.
Don't forget to shake the grinder and use it for short periods for best results.
