Do not buy this grinder! It's the loudest coffee grinder I have ever owned. I bought it cause it said supreme burr grinder and paid a lot of money for it. I had it for a few months and I got tired of how loud it was, I bought a different brand ten time more quieter and better. But if you want to leave the room or don't mind slight hearing loss, then by all means get this unit. I didn't want to be responsible for someone else hearing being damaged so instead of donating the grinder to goodwill, I threw it in the garbage. Good luck
It was great while it worked but the blade assembly. broke in half after using it 3 months.
