I love my Keurig - I have the 48 ounce one - it has worked very well for about a year and half. I do have filtered water for the house and use that. So deposits have not been an issue. When we travel I use bottled water to make coffee because I am now spoiled. Since I am the only one at my house that drinks hot tea and coffee it works very well for me. And I even order from Keurig when they have their specials - because their boxes of coffee have 24 cups (instead of 16) and free shipping. Also, they have sampler packs so I can try different coffees and teas.
