You already bought the Mr Coffee with Keurig technology machine, so the true test is whether or not you like the coffee that you make with it. You can always do a Google search to see what people think of the machine and how it compares to a Keurig. Here is a page of reviews that I found on Amazon:
saving money is good but if the coffee is good I would not mind but normally Kuerig coffee is just "YUKKKKKKKKKKKKK" can't stand them.... I was in Chicago couple of weeks ago and I needed up stay at Sofitel and they outfit their room with Kuerig coffee. I need coffee in hurry so I did brew a cup and I ended up not drinking more then one sip and bought myself a cup of coffee near the hotel... If you can brew better quality coffee, this would not be such bad way to getting your one cup....
