Keurig K-Duo Coffee Maker Review – Single Serve and Carafe Coffee Maker

Brew a 12 cup pot of coffee, or just a K-cup!

Previously, we had both a regular coffee maker, and a Keurig. I NEED both options, but I also need counter space. This is the perfect solution! But is it worth it? Keep reading!

I purchased the Keurig K-Duo a month ago, and have been using it every day.


On the carafe side, the heating plate will automatically shut off after 2 hours. I like this feature, because I tend to forget to turn it off.

You can use Auto Brew on the carafe side. You can set the brew time up to 24 hours in advance if you need coffee the minute you wake up, like I do!

Also on the carafe side, you can brew 6, 8, 10, or 12 cups.

On the K-Cup (Single Cup) side, you can brew 6, 8, 10, or 12 ounces.

The machine will power off 5 minutes after brewing a Single Cup.

The Single Cup side does not have a timer, so you can’t wake up to a prepared cup of coffee, but it does brew quickly.

Keurig is notorious for a weaker cup of coffee (in my opinion), but the plus of this model is the “strong” button. You can select strong if it’s too weak for you.

Ok, so what do I think?

Keurig Duo Review

It’s a big unit, but it’s smaller than having a separate coffee maker, and Keurig, so I’m okay with that. That’s a positive for me.

The water reservoir is removable so it’s easy to fill. It clearly marks the water level by cups. The only downside to the reservoir is that the levels are on the back of the unit, so if it’s against the wall, you have to look through to see the level and it’s backwards. Not a big deal, but I would prefer if it also had the levels printed on the side of the reservoir.

It’s really easy to use. The lights flash telling you which step you need to do next. Choose carafe or single cup, choose 6, 8, 10, 12 (cups or ounces), press start.

It brews fast. Some coffee makers take a long time to heat up, and this one doesn’t.

It’s a bit noisy when it’s brewing, but it’s quick, so it doesn’t bother me.

I was pleasantly surprised that the Single Cup side does not splash! Other ones I’ve used have splashed all over the unit, and the counter. No splash with this one!

It accommodates a larger mug. The photo below shows my 16 oz travel mug. If you have an even taller mug, you can remove the grate and set the mug in the reservoir.

I’m enjoying the Keurig Duo, and I would recommend it!

Update: Here’s a bonus tip! The descale light does not turn off after descaling the machine for some reason. It may just be mine, I don’t know. I finally found the answer of how to fix this!
To clear the Descale light, turn on the machine and press and hold the 8 cup button and the 10 cup button at the same time for about 10 seconds. Light turns off!

Update: It’s now February 2, 2024 and the Keurig Duo is still going strong! I still recommend it.

You can get yours here if it looks like something you would like too!

If you like Cappuccinos, Lattes, and/or Coffee, there’s the Keurig K-Cafe Coffee Maker too!

  1. I love the idea of this machine. We just bought this after Christmas 2020. I like not having two appliances on my countertop as we have a smaller kitchen. The only thing I’m disappointed about is that the carafe side doesn’t brew a 4 cup pot. I’m the only one who drinks coffee that way and the 4 cup pot makes me two nice cups as that is all I drink in the morning. The 6 cup pot makes too much and I waste coffee. It really should be able to brew a 4 cup pot. Also, I love the stronger feature but sadly for me it doesn’t make the k-cup brew a strong enough cup. So I am a bit disappointed but that’s just me. Otherwise it is a very nice machine.
