I bought this to grind for my aeropress but I came close to returning it. It seems very prone to blocking with fresh beans. Saved in the end, just, by the pulse feature which seems to solve the issue. A decent grinder for the money but I guess I'm spoiled having a Mazzer Major for espresso duty.
Maybe not fine enough for espresso (so my partner tells me), but spot on for pour over and aeropress.
The first unit I got had some calibration issues but the replacement works perfectly. Very happy with it.
Great entry level product, grinds well, even down to a half decent espresso, not had enough time to test its reliability, but im happy so far.
