K-Duo Plus

Great space saver! I am always rearranging my counters moving things around; Keurig is light & easy to move side to side. The water reservoir is easy to transfer side to side or attach to the back freeing up space. I love the ability to make a cup or a pot of coffee & the speed is fast ready under a minute. Great Buy & Looks Great!

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 Amazon 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.

This coffeemaker met all of our very specific needs. Our small 1970 kitchen has low upper cabinets. We needed something with a smaller footprint and a left-side reservoir so we’d have space to pour water in. This unit is shaped long and narrow instead of boxy, so we didn’t lose a lot of precious counter space. I loved the ability to change the reservoir location, which was easy to do. The pod insert is toward the back of the machine, so we do need to slide the unit out to use that (because of our low cabinets). I have the coffeemaker sitting on a tray, so sliding it is easy to do. The options do require a lot of button pushing first thing in the morning! Power on, choose strong (or not), choose pot or pod, then size, then the start button. It’s not at all complicated, and we joke that it’s our pre-caffeine cognitive test! The coffee is good (we use the “strong” option and it makes a difference). My only complaint is that the carafe does not keep the coffee hot long at all. Our cheap old Mr. Coffee carafe kept it piping hot for hours, and we got spoiled. My husband goes to work a couple of hours before I get up, and now I have to nuke my cup of coffee to reheat it if he makes a pot, which I didn’t have to do before. But, considering all the other issues it solved for us, I don’t mind. Having the option to do Keurig pods when we want something different (decaf, flavors, hot cocoa), or when we have company who want whatever we did not make a pot of is really convenient. Overall, it’s been perfect for us.

I live alone, so Keurigs have served me well, and of the several I've used, this one is my favorite so far. Although 95% of the time I prepare individual cups for myself, it's fantastic to have the option of making a full carafe when I have guests, and the thermal carafe keeps the coffee hot without cooking it as bottom burners do. It's a fantastic two-in-one device.PROS: small footprint, choice of three positions for water tank, carbon filter (optional), works well under standard 18" counter height, lighted programmable LCD display, lighted buttons, intuitive interface, looks nice, comes with gold reuseable basket for the carafe, and makes great coffee! Also, I use the reusable universal K-Cup filter and it works great in this model too.CONS, which I'll address individually:1. Because of the carafe height, the dispenser for the single-serve is also pretty high above the tray and can lead to splatter. So I simply place a former ceramic candle holder under my coffee mug to position the mug closer to the dispenser when I prepare a single-serve cup. Problem solved.2. Because the single-serve filter is positioned behind the large basket for the carafe, there is a little channel about 2" long that transports the single-serve brewed coffee toward the front and dispenses it just behind the carafe dispenser. Pretty ingenious design, though you'll need to remember to remove and clean this plastic channel piece regularly too or coffee oils could build up in it; fortunately, it's easy to remove and put back in.3. The biggest room for improvement, imho, is that there is no way for the user to adjust the temperature of the water. Keurig should add this, for sure. In single-serve operation, the brewed coffee travels trickles down the internal channel mentioned above, instead of dropping directly into the cup. And I think this makes it lose a few degrees of temperature in the process. I usually have to nuke my coffee a few seconds because it's just not hot enough straight out of the Keurig. If I could increase the brew temp myself, the problem would be solved.But overall, I'm really happy with this model and would buy it again.
