Way cool! I think life on the burrset is 600-lb but, if they crapped out tomorrow you're only taking $40. My burr test is any sediment in press coffee.
Some guys get creative and slice the hopper down several inches to "under-kitchen-cabinet" height. The more clever amongst them first lined up the a correct diameter lid before putting saw to hopper. A replacement doser lid fits nice on the Mazzer-Mini hop-chop, good for about 1/2 pound in the bin.
