Not great...
I didn't care for this grinder. It creates a ton of static when it's grinding so that the grounds stick to the cup, the grinder, your hands, everything, and make mess. It's also a bit of a pain to have to make sure the lid is completely locked before grinding... if you get a bit of grounds in the locking area, it gets very finicky. It also won't grind the beans evenly. I get beans crushed to powder and nearly whole in the same cup.
