Overall, excellent machine to make quick, awesome coffee drinks, but it takes a bit of effort to figure it out. Also, it's very important to keep up with the internal cleaning and maintenance schedule. I highly recommend using either the tank filters or your own filtered water for the tank. I use a Zero Water pitcher, separately for the waster source. Never consume straight tap water. Anyways, keep an eye on those internal o-rings. They wear out, especially if not lubed, and you'll have a lot of dump water in the collection tray with each use
