Ease of Use

Hamilton Beach Flexbrew

This is a very straightforward design, making it user-friendly.

The digital clock is easy to program as is the scheduled brew timer, and brewing the coffee itself is simple.

To brew a single-serve cup, simply press the button, lift the lid and place your either reusable or disposable K-Cup in position before closing. Next you add water to the reservoir. Finally, choose between regular or bold flavor for your coffee by pressing on Brew Strength and hit “Brew Now.”

To brew a carafe you will use the carafe button and the water reservoir. Make sure to put a paper coffee filter into the brew basket (one for every cup of coffee you want to make). Then, fill it with one tablespoon of grounds per cup.

Keurig K Duo Coffee Maker

A quick start guide is included to get you set up at home with the Keurig K Duo. The K Duo functions very similarly to the Hamilton Beach Flexbrew.

This machine requires that you purchase the reusable K-Cup and paper filters separately, which can be a little frustrating. You will also have to buy the Keurig Gold Tone Mesh Filter if you want to use this coffee maker for carafes.

The fact that none of the parts of this machine are dishwasher friendly and are not all included, does make it slightly less user-friendly.

Brew Quality

Hamilton Beach Flexbrew

I have found this product to provide great consistency in flavor. When I bought a specific brand of coffee grounds and then bought that same brand in K-Cup form, the Hamilton Beach Flexbrew brewed them so they tasted just the same.

You can expect consistency in flavor and quality whether you choose the single cup or the carafe option.

Keurig K Duo Coffee Maker

This is because all four of the cup size options are pre-programmed in this product. This makes it easier to not pour too little or too much water into the tank when you’re in a hurry, as you might with Hamilton Beach Flexbrew. Therefore, this product also produces consistent cups of coffee that come out with standard measurements every time and doesn’t require any measuring on your part.

The carafe option also produces really aromatic and delicious high-quality coffee.

Cleaning & Maintenance

Hamilton Beach Flexbrew

I believe that the ease of cleaning is one of the main benefits of choosing this machine.

If you find that your coffee is not being fully dispensed when it’s brewing, your needle may be clogged. It is a simple fix to unclog it though.

You have to unplug the machine, then turn the needle holder counterclockwise, and use a paperclip to clear out any grounds from the holes in it.

Next, flush the needle holder with water. Then put it back and lock it into place by turning clockwise. Finally, brew two to three times with just cold water to make sure the coffee grounds have all been removed.

You can help prevent future clogs from happening by always letting your machine turn off automatically after every cycle. You should also make sure to remove the coffee grounds or pod once the machine has cooled so that it doesn’t dry up and create a mess in there.

If you want to descale your machine pour ¾ of a cup of white vinegar and ¾ of a cup of water into the reservoir then press brew now, without adding any coffee. Once it has begun to brew and you see the solution pouring out, press the brew button again to stop it. Now unplug the appliance.

Wait 30 minutes, then resume the brewing cycle. Once it has finished, run two to three cycles with cold water to flush all of the solution out.

One of the best things about this coffeemaker is that all removable parts are dishwasher friendly, making them easy to clean.

Keurig K Duo Coffee Maker

Keurig recommends buying their descaling liquid and using a one-to-one ratio of it and water to descale the machine.

To descale your machine you will first pour the solution you made into the water tank. Then brew a 12 oz. cup with no coffee grounds or pod. Afterward, empty the contents out. Then do the same with 12 cups in the carafe.

Let the machine rest and cool for 30 minutes without powering it off. Then come back, rinse out the carafe and reservoir, and brew three times with water.

Overall Value: Which One Is Better

The K Duo’s single-cup option saves time by using a large tank that the machine will pull from. This means you won’t have to keep pouring water in when serving coffee for yourself or your family members. I find this to be one of the best features about this machine!

The Hamilton Beach offers a lot of value for a lower price point. It is compatible with K-Cups, reusable K-Cups, and regular coffee grounds giving you many options to enjoy your coffee. Alongside the adjustable brew strength it has this makes it incredibly versatile.

One of its best features, and what sets it apart from the K Duo, is that it has dishwasher-safe components. The convenience there is unmatched. For the price and all of the features it comes with, Hamilton Beach Flexbrew is a solid choice.


The Keurig K-Duo is an excellent choice if you plan on making multiple cups of coffee in a short period of time. If you are on a budget and love when your appliances have dishwasher-safe components, the Hamilton Beach Flexbrew is for you! Either way, whichever maker you purchase will end up with high quality coffee that can be adjusted to meet the various needs.
