Keurig K-Duo Hot & Iced Single Serve & Carafe Coffee Maker, MultiStream Technology, 72oz Reservoir (Gen 2)

I’ve had the Keurig K-Duo for a little while now and have been very happy with it. What I like most is being able to make a single cup when it’s just me, but still having the option to brew a full pot when I want more coffee or have company. It’s easy to use, doesn’t take long to brew, and I like not having two separate coffee makers sitting on the counter. I didn’t think I would use the iced coffee setting much, but I’ve actually used it quite a bit. The controls are straightforward, the coffee comes out consistently good, and overall it has just been very convenient. Nothing overly complicated or fancy about it—it simply does what I need it to do and does it well. That’s really all I was looking for. I’m very happy with the purchase and would definitely buy it again.

I just got my Keurig K-Duo today. I just gotta say I absolutely love this machine! The size is just right for countertop use. Everything is very easy to operate and I love all the brewing options. It cost more than I wanted to spend, but now I believe it was worth every dime.

I bought this on Jan 2 and have been using it for only 24 days. Today I continued to get a "add water" message (with a full tank) and "error 8" message followed by "dry". I cleaned the tank and re-filled several times and unplugged the machine to re-set it as online has indicated. I was finally able to get the machine to brew. Mind you this is a brand new machine and after 24 days has issues. I use filtered water so this should not be an issue. I have notified Keurig to see if there are solutions to fix these issues. I will keep this rating updated, but use caution when purchasing this machine. EDIT: So I have been able to get the coffee machine to work once again. After getting errors, I unplugged the machine for a period of time, flushed out the water tank, and plugged it back in with fresh water. I was able to get it to function normally for the past several days. I use the timer and it have brewed coffee without issue for a few days. The single use side is functioning normally. Don't know if unplugging it reset whatever chip is inside but it works for now. If it continues to function normally over the next few months I will change my star rating. For now, I am skeptical of long term use. 02/08/25 UPDATE: DO NOT BUY THIS MACHINE!!!!!!!! I experienced same issues as listed about. Tried to repeat the "fix" three times without success. Contacted Keurig, but I am not optimistic I will receive a full refund. Amazon also closed my ability for a return on 02/01/2025, so I now can ONLY DEAL WITH KEURIG. If I could give zero stars I would. 02/28/25 ANOTHER UPDATE: Was able to finally get Keurig to send me another machine on 02/16/25. On 02/28/25, I received the new machine. Unpacked and carefully followed the directions to the "T". Plugged in the machine as directed and it failed to turn on. Tried a different outlet, nothing. Tried another machine and it powered up without issues. Not an outlet problem. It was clearly a machine problem walked around the house trying the machine on various outlets, nothing. Called Keurig and they ran through troubleshooting, nothing. Machine DEAD ON ARRIVAL. They tried to tell me since this was a warranty replacement machine, it no longer was subject to warranty. EVEN THOUGH THIS MACHINE WAS DEAD ON ARRIVAL. I was able maintain my composure and convince Keurig to send me another machine, which will be here in 7-14 days. Stay tuned folks! BTW way, my first machine still has the above issues and continues to periodically stop working, then work, then not work... I would love to have my money back, but Keuring rather spend more money on shipping and returns than refund my purchase price. Come on Keurig, you can do better. EDIT: 04/20/25, ANOTHER UPDATE. Since my last update on 02/28/25, I received a third replacement machine from Keurig to replace the dead one. Got #3 all set up on 03/03/25 and ready to go and it worked until 03/28/25, exactly 25 days, then I got the dreaded "add water" and "error 8" message. Called Keuring and asked for a refund, but they still refuse since I bought it from Amazon. Asked to get another comparable machine, which they didn't have in stock (UGH). Ordered #4 replacement. On April 3, 2025, #4 replacement machine arrived. Got #4 all set up and on 04/20/25, it stopped working like the others. This one only lasted 17 days. EDIT: Keurig has started ignoring my calls. I was referred to a "specialist" who told me I needed to send my #4 machine in first BEFORE I could get sent a replacement. As I did not want to send them my machine without a replacement first, they started ignoring my emails and are now refusing to correspond with me at all. #4 machine continues to brew 2 cups then shut off reporting it is dry when there is a full water tank. I will never purchase another Keurig product and you should seriously consider doing the same. Four unusable machines in 8 months is ridiculous!

This shipped so quick and was easy to unpack and install. I love that it’s not super bulky on my counter and I have the option to make a quick cup or make a pot on the days we have company or feel like it’s a multi cup morning. IYKYK!! The KCups are easy to use and comes up a great brewed cup every time. The brew is quick and hot! To pot is easy to make. The lid in the back comes off easily and I just pour water into the reservoir. I would highly recommend!

This is the perfect combo edition. I have been replacing my regular Keurig about yearly because of use. When I work I have one cup, but when I work from home or have days off I can drink 3 cups. My wife also has one to 2 cups a day depending if I am home or not. When I am home brewing the pot is a lot more convenient and better for the system. Best deal for us.

Love this coffee pot, does everything very well but the water reservoir is begging to crumble, it now has a crack that is beginning and a hole has began at the top of the water well, not sure what to do.

The Keurig K-Duo Single Serve & Carafe Coffee Maker is an absolute game-changer for households that want both quick morning speed and full-pot brewing capability. By seamlessly combining single-serve K-Cup convenience with a classic 12-cup glass carafe, it replaces two separate appliances with one sleek, space-saving countertop setup. Brew speeds are impressive on both ends. Single-serve pods deliver a rich, flavorful cup in under a minute, while a full 12-cup pot brews in just a few minutes without over-extraction or bitterness. The control panel is intuitive, with clearly labeled buttons for cup size and carafe settings. Maintenance is equally straightforward, featuring accessible filter baskets and clear fill indicators. The Keurig K-Duo hits the sweet spot between weeknight simplicity and weekend batch brewing. For anyone seeking speed, versatility, and dependability without cluttering their kitchen counters, this coffee maker is an exceptional choice.

THIS MACHINE IS GREAT! USING IT AT THE OFFICE & IT HOLDS JUST ENOUGH WATER SO WE ARE NOT ALWAYS FILLING IT AND IT BREWS EXCELLENT TASTING AND TEMPERATURE CUPS OF GROUNDS! AND PODS! i ALSO GOT THE BASKET FILTER AND 2 LITTLE BASKETS FOR THE PODS AND THAT HAS REALLY CUT DOWN ON GARBAGE AS WELL! AND THE COLD BREW IS ALSO GREAT! GREAT MACHINE ALL AROUND HIGHLY RECOMMEND SPENDING THE MONEY ON THE NAME BRAND! 5 STARS ALL DAY!

Très contente de mon achat

Excelente opción para oficina pequeña muy aguantadora y fácil de limpiar

Al principio dudé hacer la compra por el precio, me pareció algo elevado en su momento. Me animé hacer la compra y la verdad, vale cada centavo. Es una alivio poder utilizar las k-cups y/o la cafetera regular según el momento del día y la cantidad de servicios requeridos. Todo funciona bien y súper sencilla de usar.

Bought this to replace my Nespresso that I HATED. instantly hot and works perfectly especially when I program it to brew in the morning

Love it, large reservoir both sides pulls from it, fast and very hot
