Keurig K-Duo Plus Single Serve & Carafe Coffee Maker, Multi-Position 60oz Removable Reservoir, Programmable Auto Brew Carafe, Black

Perfect for our kitchen
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.

Very versatile coffee maker
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.

I received my duo via Amazon but when I ordered it didn’t specify that it was from Costco. They shipped quicker than expected, and included a bonus 1 lb ground coffee, 48 KCups and a spare coffee machine filter. So I was already impressed before even firing it up.Love the slim design and removable water canister that can be placed on the back or side. Love not having to fill the pot with water first then pour it into a coffee maker, usually ending up with water on the counter.The design allows me to make a pot of coffee and then use a KCup function or just straight water through the KCup function without having to remove the full pot coffee filter. They function through two different places. This important to note because if you want hot water for tea, it doesn’t run through the full pot coffee filter area and taste like coffee.The coffee comes through hot into an insulated pot instead of warm and heated on a burner resulting in a bitter cup of coffee. Note, there is no burner. This actually works well for us as having a water softener, as with our other coffee makers, on occasion after washing the pot and placing on the burner, the salted water has corroded other coffee pot burners.Anyway, the flavour of the coffee is superior to any other coffee maker I have had.Now, the one flaw; insulated pot doesn’t close completely so the coffee stays “warm” for two hours as advertised. Warm, not hot. Since my husband leaves for work before 5 am and coffee is timed for him, by the time I get a cup shortly after 6 am, it is warm, not hot. If I add cream, I have to reheat it in the microwave. This is a small point, not major but if you think it keeps the coffee hot for two hours you would be disappointed. The coffee is good enough to drink black though so without cream, it’s usually warm enough for the first much needed cup.

This machine takes up much less counter space than the earlier K-Duo, which I replaced after breaking two glass carafes, which are very expensive and slow to be delivered. It takes up less counter space and the water tank is easier to handle. It brews more quickly and the insulated stainless steel carafe keeps the coffee hot longer than the old one, which switched off automatically after a period of time. And hopefully, this carafe is unlikely to break.
