Tjyven So far i only have the Stock burrs to play with.. I am really enjoying the output from this grinder, from Workflow to Taste. The espresso flavours are very well balanced/sweet and smooth. Clarity is certainly not its strongest point, but the balance and sweetness easily makes up for it.
Interested for filter using this stock burrs also provides very good brews. The Mazzer style burrs, when used in conjunction with this grinder, outputs very little fines which is very surprising, given the experience i had with other grinders with similar burrs.
