OXOOn Conical Burr Coffee Grinder with Integrated Scale by OXO

Anyone find the grinder didn't work at all despite calibrating, cleaning, and turning on etc?

Has anyone used this for espresso grind? How is the consistency/grind size?

I've had burr grinders where the grounds get stuck under the burrs and in the chute that goes to the grounds container. Does that happen with this?

How much of a hassle is it to clean?
