Customer Ratings & Reviews

Overall we are happy with this purchase. 3 stars only because pouring the coffee from the pot is a challenge. It's a bad design and usually makes a mess. Brews fast and the single serve works great.

The finish on the warming plate for the coffee pot is already peeling off and it is only 26 days that I have had it.

I like the idea of having the carafe and the pods. Unfortunately, when using the carafe the coffee is not an ideal temp. I have to microwave it to warm it up. Wouldn’t buy it if I’d known that was going to be an issue.

I like the two ways to make your coffee, but hate that you can't reset the warmer plate. Once it goes off, the only way to turn it on again is to make a fresh pot of coffee. Also, sometimes it leaks water all over the cabinet. I thought it was our fault when filling, but even after being extra careful, it still does it once in a while.

Overall, the K-Duo 12-cup coffee maker is average. It heats fast and brews well. The auto brew function is convenient but does not allow for the option of a strong brew. Be careful not to pour too fast, the coffee pot lid has the tendency to leak out of the top. Good daily coffee maker.

Nice, but temperature of coffee is not that hot. The coffee maker seems to always leave about 2 cups of water in the reservoir. Not real sure I would purchase this again if given the opportunity.

We have been happy with the coffee brewed using the Keurig K-Duo, however brewing/noise is rather loud. Also, it was difficult to find a water filter starter kit. Had to order. Disappointed that it was not included with the Brewer.

It brews good coffee, but there is no permanent/reusable mesh filter made for the carafe side. Paper filters will sometime leave the enclosure full of difficult to clean grounds. Too bad because it is an otherwise good coffee maker.

This coffee maker brews a decent cup of coffee, and I love the single serve feature. It also has a reservoir so one doesn’t have to fill it with the exact amount of water for the amount of coffee one is brewing. It does not have a 1-4 cup feature, and and a 6 oz single serving is the smallest it will brew, so I either use a lot of k-cups or brew just a bit too much coffee (it’s just me in the house). But setting up the delayed brew ( I set up the coffee machine the night before) has me scratching my head! It would be perfect if I brewed the same amount of coffee every day, but I don’t so I’m never sure if I have the right amount of grounds for the amount of coffee the machine wants to brew, if it does at all! It shouldn’t be rocket science.

Overall this machine is nice, and worth purchasing. It does have a glaring flaw though regarding the burner for the carafe. There is no option to simply turn the burner on without brewing another pot. This is a terrible oversight when paired with the fact that if one brews a cup after making a pot it shuts the burner off. Also a problem if someone accidentally hits the power button or cup button right after. This is an issue if you have someone that only drinks decaf or tea as you can't just make them wait for you to finish the pot. How this made it past QC is beyond me as it is quite the oversight for the cost of this machine. Giving it a 3 out of 5 because outside of that the machine is solid.

I was very excited to buy my first Keurig. The K-Duo is a beautiful design both cosmetically and functionally. My wife and I wanted to brew big pots in the morning and either single serves when it was only one of us or for a cup of coffee or tea during the day or afternoon. It worked great for a few weeks. We may have ran into the same problem another reviewer did. We start to brew the pot and it stops after only a small amount and won't finish the pot (wasting our coffee). I then hear what sounds like a pump and/or motor going until the unit turns off. I will be contacting Customer Service and/or returning. I really want a replacement and I hope this is simply a rare defective unit, not a problem with K-Duo in general.

i love that i can make a full pot or have a single serve cup of coffee. I am always in a hurry so being able to pause the brewing so i can pour a cup of coffee is great. No drip mess, the pot turns itself off after 2 hours. I like that you can set how strong you want your coffee and that you have 4 different cup size options to pick from. I love everything about this coffee maker but one thing has me a little put off. FOr some reason I have to continuously open the k cup holder and shut it a few time before the single serve cup will brew. I almost have to slam it down for it to start brewing.

Not what I thought it would be. Since it a daul brew though I would be able to use each at same time. Husband drinks pots of decaf a day. I either dink dark roast regular coffee or tea. As I work and he is disabled and home all day I use single brew side I dont like the fact that you have to turn pot off to use single brew side. Also cannot turn warmer on independant ly. will be replaceing as soon as can find other modle that meets my needs.

The K-cup side of the unit is temperamental. It stopped working at the 16 day mark, and took some troubleshooting to get working again. Sometimes when running the K-Cup side it spits a not so insignificant amount of water out into the pot as well. This unit is finicky, and I don’t expect it to last more than a year. However, it looks nice, and works well often enough that it isn’t worth the hassle of returning under a warranty. Buy when on sale, and be aware of poor quality control. Use it heavily in the first 2 weeks to avoid missing the return window, in the case you got a bad lot.

This coffee maker is handy in that it replaces two items that were taking up space on our counter. It makes excellent coffee. However, strangely the AUTO feature that one would expect is set up to make coffee at a selected time (like in the morning) works only on the single-cup side, NOT on the 12-cup side. Had I known about this shortcoming, I would not have purchased this unit.

It's a great space saving design. However, you can't make a single cup while a pot is brewing and it is impossible to pour from the carafe without it spilling each and every time. It would have been great if I could use my old Mr Coffee carafes instead, but they made theirs 0.25 inches taller so they don't engage the anti-drip button properly. I hate when companies make stupid little changes just to lock you in to their parts and service. We're keeping it because it's convenient, but when it inevitably dies we will definitely be buying another brand.

Would've gave it five but there is two big problems. 1) the pot leaks like a siv, I remember my mother's having a similar issue. 2) the reserve tank has to be filled a bit while brewing or it says add water towards the end. The individual maker is nice though. (Didnt come with single brew ground k-cup, disappointment)

While it works and is OK when you push the on button and wait for the water to heat up if you aren’t quick it shuts down and you have to start over again. Drives me crazy. I have also had to reset it twice because when you put the pod in it won’t start brewing. After you reset it is OK for awhile.

It is a great coffee maker. Instead of having two different coffee machines this does save you space. My only negative here is the tank being very small and have to refill after a couple cups of coffee. Also it does not come with the water filter holder so you’ll need spend another $20 on that.

Love the concept of the duo. Can make coffee for large groups of folks if they come over, or just a single cup in the morning if I am feeling lazy. The problem is the machine stopped working almost exactly 1 year after purchase. Luckily I got the warranty from BBY taking it back to exchange. Will give the duo one more shot before switching to another coffee maker/brand.
