I purchased this for more counter space.   First one I received gave me 8oz or less on a 12oz level.   Also when the water reservoir got just below half way it asked for more water.  I called Keurig and they said I must have a defective one.  They sent me out a new one with no issues and even gave me 2 free boxes of coffee.   Received my replacement maker and it did the exact thing with the exception of every few coffees it did give me 12oz worth.   Returning it today.
