I just got one of these things, around a month ago. This machine has told me to replace the water filter, btw which Keurig sells, 3 times. There is no way it needs to be changed that many time, at all. Especially since, I use very pure mountain water to fill it with. No I don't mean bottle water, I mean the real things from a nice pure fresh natural source. I can only imagine how many people bought a new filter every time that thing told them to. With 0 understanding, if it honestly needed to be changed or not.
This is why I extremely hate mmo cash shops. They are literally designed with the same evil, hidden messages, to get people to spend money, even if they really don't know why, or even if there is a purpose to the thing they are buying.
