This grinder, while if feels well made, has some serious design issues. The most serious issue is how quickly the unit clogs up and needs to be cleaned thoroughly. The cleaning is much harder than it should be, even with the brushes that were included. Additionally, the amount of static generated by this grinder is outrageous, coffee grounds fly everywhere around the unit and behind the collection container. The amount of coffee bean debris that are cast off is significant and cleaning these up is a considerable chore. I absolutely do not recommend this product, steer clear at all costs.
