Follow up to my original review. After 10 months this machine has exceeded my expectations. This may be the best coffee maker I have ever owned. I bought this machine July 12 for $140. I owned a 10 cup Mr Coffee machine that had similar functions and features (except the K-cup capability) that I was very happy with. It was about 10 years old when it started leaking water from the reservoir which prompted me to replace it. The only issue I had with the old machine was capacity. On those occasions when my wife and I wanted an additional cup of coffee it was inconvenient to brew another half-pot or full pot that often didn’t get fully used. This Keurig Duo seemed to be the perfect replacement. It features a 12 cup pot and has the K-cup feature for additional cups if needed. After reading several reviews on keurigoutlets.com I identified 3 items that were a concern to me. 1. The permanent filter lets fines into the carafe. 2. The carafe doesn’t keep the coffee hot enough, long enough. 3. Longevity, a few reviews noted breakdowns after a few months. I have only owned this machine for about 2 weeks so I don’t have enough history to speak to the longevity issue. However, I can say that my first two concerns have been non-issues for me. The permanent filter DOES let fine coffee grounds through into the carafe. This problem is easily solved by using paper Bunn Coffee Filters BCF100 in place of the permanent filter. This works so well that in my opinion it renders the permanent filter a detractor rather than a benefit. The filter basket holder is easily removed and you can dump the filter and grounds out cleanly. Conversely the permanent filter has to be removed, cleaned and put back. In my estimation this is far more inconvenient. As far as temperature is concerned I find the Keurig carafe is probably less insulated than my old machine in that it seems to cool off faster. This is also not an issue for me. My perfect drinking temperature is somewhere around 145 degrees. The temperature of the coffee from the Keurig is 170 degrees right after brewing and is 168 at 30 minutes and 161 after 1 hour. The coffee pot is usually empty before the two hour mark in our home. So far the temperature has not been an issue for us. Other miscellaneous notes are: brew time for a full carafe is 9 minutes and 30 seconds; very reasonable. The auto delay brew function works well but is a little counterintuitive. I have to turn the machine on, push the auto button, and press the start button to “set” the delay function, then press the power button again OR it will brew a pot of coffee immediately. Counter space footprint is ideal for us. Registration of the product was slightly inconvenient because the Keurig registration system didn’t recognize the serial number at first. I tried again after a few days and it worked fine so not really a significant issue. Overall – after 2 weeks of ownership I am very satisfied with this product and would recommend it highly. If it doesn’t last for at least 5 years at the current price point however, I would not buy it again. Time will tell.
