As previously mentioned, this grinder is a bit less sturdy than its new revision, the 565. The 560 has the same issues with its mechanical timer, with the grind mechanism starting before you have had a chance to set the time. This results in a somewhat inconsistent grind quantity. The hopper lid is also not completely airtight, so it isn’t recommended that you keep your beans in it for more than a few days. The same issue with static buildup is also present, and may lead to a messy countertop.
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.
