The first notable downside to this economy grinder is the build quality. Although it is standard for high-end burr grinders to use stainless steel enclosures, the Capresso 559 is built from a cheaper plastic. Beyond its suspect longevity, the cheaper build also causes problems in functionality. For example, beans can jam the grinder chute, causing the machine to stop functioning until it is cleaned.
3) This machine is crazy smart. It knows exactly when to clean itself, or tells you when to start the cleaning cycle. To clean it, all you do is insert a tablet in the coffee powder drawer and it does its thing. It knows when it needs water, when the filter needs to be changed, etc. In fact, since we have a water filter built into our refrigerator, we just use that filtered water in the coffee machine and therefore we don't need to use the expensive water filters. Bottom line, if you just pay attention and clean the machine on a regular basis when it tells you to, this is a no-brainer machine.
