There is more to the Keurig K Duo Coffee Maker than just its good looks. 

This specific type of coffee maker has made a positive impression based on most Keurig Duo reviews published online – and for the right reasons. There is no doubt about the stylish design being easy on the eyes for most people.  

It also has a number of wonderful practical features that truly match the exterior beauty. Some of these are unique and others are expectedly commonplace among first-rate coffee makers.

Design and Construction

True to its namesake, this coffee maker literally has two ways of serving you with the best cup of Joe. In fact, almost every Keurig Duo review featured on the internet is keen on mentioning how the two main dispensers prove to be a clever design. This coffee maker sports a rounded compact form and visually appealing to anyone who values ‘equal proportions.’


This coffee maker looks evenly-shaped, with a size that is quite intimidating. It measures 12.92 inches in height, 10.94 inches in width, and 12.76 inches in depth (12.92 x 10.94 x 12.76). You would need to allocation ample space in the kitchen for this neat-looking machine. 

The Keurig Duo Coffee Maker weighs around 14.4 pounds. So place it on a stable surface or a durable kitchen countertop. You would also need serious muscle power to move it around.


Like many popular coffee makers, this item is made from smooth black polymer with silver metallic trims. Its texture proves to be an asset, especially if one chooses to buy appliances for its aesthetic value. 

Its carafe is made of glass and a lot of people might consider this delicate material as one glaring limitation of the Keurig K Duo Coffee Maker. However, the transparent view behind the glass container provides better measurements, especially with the 12-cup limit metric volume engraved on it.  

Safety Features

One of the most wonderful features we really like about this coffee maker is that it features an automatic shut down after it is left unused for 5 minutes. Within 2 hours, the heating plate also automatically turns off. Not only is this machine safe, but it is also very cost-efficient.  

As often featured in most of the Keurig K Duo reviews, this coffee maker also has a ‘Pause & Pour’ feature. This gives you a 20-second automatic stop to its brewing process if you are in a hurry to grab a cup.

Accessories Included

The Keurig Duo Coffee Maker did not earn its reputation as a brilliant piece of technology if not for its neat accessories. It is important to take note that this coffee maker has two ways of brewing your cup of Joe. One slot brews via the traditional coffee filter and dispensed directly to the carafe. The other one beside it (the single-serve side) receives ‘coffee pods’ and then poured directly into a single cup. Some online sellers include these K-cup pods in the item purchase. 

As mentioned earlier, this coffee maker comes with a see-through glass carafe. It also has a removable reservoir that stores up to 60 ounces of water. The single water reservoir is used by both brewers.

Brew Time

When it comes to the actual duration needed for brewing your coffee, it is important to remember that it is highly dependent on the volume you prefer. 

The Keurig Duo Coffee Maker has a fixed brewing temperature that ranges from 170 to 190 Fahrenheit. These are the measured brewing time for each of these quantities:

  • 6 cups = 5 to 6 minutes
  • 8 cups = 6 to 7 minutes
  • 10 cups = 7 to 8 minutes
  • 12 cups = 8 to 9 minutes

Keurig K-Duo 2 Way Dimensions

A two-way coffee maker gives you the option of choosing which brewer you prefer on a certain day or moment. If you are yearning for a coffee with a much stronger and bolder taste, most of the Keurig Duo reviews recommend the coffee pod brewer pouring through the single-cup dispenser.

Single-cup coffee pods produce an intense flavor because it is designed to slowly press the coffee grounds tightly through its cup (pod). This route produces a higher concentration since it only serves a single cup, and is not diluted by the amount of water needed to otherwise fill the glass carafe.

Designed for dual-brewing action. Your next cup can be made using coffee ground or K-Cup pods, depending on what suits your fancy at whatever time of the day.

Ease of Use

Aside from the fact that you can remove and fill the water reservoir straight from the tap, this coffee maker is a simple machine to operate. Many of the online Keurig K Duo reviews highlight the capacity to be programmed 24 hours in advance. 

The Pause & Pour feature is another advantage you can enjoy with this coffee maker. Basically, you can remove the carafe from the brewer within the 20-second window pause. Do not go beyond the timeframe to avoid accidents.

Serve 6, 8, 10, or 12 cups of coffee straight from the standard filter brewer. Luckily, you can easily choose and press a button for each volume. No need to perform a series of manual steps.


This coffee maker has a number of removable parts and each of them can be cleaned by hand washing. Unfortunately, they are not safe to be placed in a dishwasher. Like many coffee makers, calcium buildup from the water’s mineral-rich content is both unavoidable and may cause damage after long-term use. It is rarely mentioned in many Keurig K Duo Essentials Coffee Maker reviews but it is highly recommended to ‘descale’ the brewer after every three months to prevent permanent malfunction. 

Brand & Customer Service

Founded in 1992, the brand name Keurig is directly a namesake of the Dutch word ‘excellence.’ True enough, they have done an excellent work of pioneering the more convenient and innovative use of coffee pods in a brewer. This brand was named Single Serve Brand Coffee of the Year for four consecutive years – from 2012 to 2015. 

In terms of customer service performance, Keurig garnered a largely positive review from a number of websites. Consumer Affairs rated it 3 ½ out of 5 stars based on the 212 ratings submitted in 2018. The company website also has a  Customer Service support page (1) that serves as a great guide. 

Amazon’s Keurig Duo review did not leave any relevant warranty details. But according to its support website, this coffee maker has a 1-year limited warranty. For more information on this matter, you may contact their toll-free number at 1.866.901.BREW (2739).

You should also register your coffee maker (2) with Keurig to get discounts on your next beverage order. Now that’s great customer service and care. 

Value for Money

Based on the many Keurig K Duo Essentials Coffee Maker reviews featured online, it is safe to say that you are hitting a gold mine with this coffee maker in terms of its overall value. You will be spending a few bucks above the $100 price range but always remember that you are buying a versatile two-way machine. 

Furthermore, there are promos that throw in Keurig’s own supply of Green Mountain blend (bags or pods). You are getting the best value from purchasing this unit. You can rarely find a better deal that includes an ample stock of coffee.   


A reliable and objective Keurig Duo review must be fair in terms of mentioning both the advantages and flaws of this coffee maker. As it happens, this machine is not without its flaws.

One of the most obvious limitations concerning this coffee maker is that you cannot adjust the temperature. This means its brewing time is always constrained and it makes a poor device for someone who lives totally spontaneous.

Another important downside worth mentioning is that this coffee maker has a total of 9 different components. Cleaning each one of them is a painstaking task, but something you need to do regularly.

Who Should Buy this Coffee Maker? 

The Keurig K Duo Coffee Maker is an ideal machine for anyone who appreciates variety and simplicity. It is worth mentioning that you can detach the lower surface under the single-serve dispenser to make room for a somewhat tall travel mug. For those who cherish options, having a two-way coffee maker is always a winner.

This coffee maker is also ideal for those who value the efficient use of electricity. Its auto-shut features also prove useful to anyone who tends to forget that they left the coffeemaker on.

Final Verdict

Anyone who loves to savor their coffee break can easily fall in love with this two-way machine. The carafe server can accommodate up to a dozen people, which is very appropriate for a relatively large number of guests joining you in a conference or outdoor (or even just a backyard) camping. The single cup coffee pod server is best for solitary moments, whether you are working at home or deeply reflecting on something.  

This coffee maker also makes a fine choice for anyone who likes to be a connoisseur of coffee pods. According to Amazon’s Keurig Duo review, you can pretty much use pods from other manufacturers and you can have the luxury of exploring unusual brands. 

Given its clever design, ease of use and energy efficiency; you cannot fault this coffee maker for its price range. Hence, it earns the overall rating of 4.20/5.
