The Comandante isn’t really a grinder as many grinders are but rather a surgical slicer that cuts with precision for the rich clean cup your precious little bean is capable of,period! If you’re not getting that result the burrs you’re using aren’t up to it. Think of them as fine knives. I’ve worn out other popular grinders that made all different sizes of pieces and dust from the time they were new. Start sharp and stay sharp are my thoughts. This is a quality, fun machine, without toxic materials like aluminum in it. If you try one you will appreciate it. Thanks for thinking this through and making it available for us who understand what it is
