I purchased it on line fron one of the sponsors. Never grinded fine enough for my machines...sent it back after re-calibrating it according to Baratza instructions, still not grinding properly. They change a part and send it back to me (so far shipping cost $50.00... ) Still not good....I told them to test it before returning !!??
They do not respond to my e-mail and so is the Baratza company...!!
Conclusion : NEVER buy on line; Check product immedietly before crushing the box....
