In general, they share the same working way as the traditional Keurigs do: pop in a K-cup and brew. But with the addition of 2.0 brewing technology, you can program the coffee strength and choose your desired cup sizes out of the 10 available sizes, which range from 4 to 30 ounces.

And whatever models you are about to use, you can brew a single cup within minute.

The models which introduce 32-ounce carafe and the number of K-carafe packs allow you to make up to 4 cups in a brewing time. And the whole time to finish this process is around 3 minutes- a bit longer compared to brewing a single cup.

Keurig 2.0 main features

Keurig 2.0 brewing system comes with a number of outstanding features, some of them can be summarized as follow:

  • They are amazing single cup coffee makers for personal use
  • Rather than single cup, you can now brew a small carafe of up to 4 cups from a single compatible K-Cup.
  • The brewing process is adjustable to suit K-cup, K-carafe, or Vue pack which is being used.
  • You can select the coffee strength as your preference.
  • There are up to 10 brewing sizes to choose from.
  • They introduce a big water container
  • The auto on/off feature is available
  • The drip is removable, making it easy for tall mugs
  • The touchscreen is clear and easy to read
  • There are 4 languages for you to choose from, including English, French and Spanish.

Types of coffee that can be used

The types of coffee can be used depend on your cup size option, particularly:

  • Small cups size of 4, 6, 8, and 10 ounces work only with K-cups with special encoding in the lids and produced after July 2014.
  • Large cup sizes of 12, 14 and 16 sizes match only Vue packs, which are slightly changed to work with the 2.0 system.
  • Small K-carafes are required when you want to brew a small carafe of coffee, of course. And now, there are 10 different flavors for you to choose from.

Multi-function options

When the machines are not inserted with a K-Cup or K-carafe, they can be used to very quickly produce hot water to make hot tea, chocolate, other hot drinks, oatmeal, and the like.

While the K550 model comes with a button for both dispensing and holding down hot water, other models are able to produce hot water during brewing with no need of a coffee pod.

When K-cups are added, the machines can directly make hot chocolate, iced tea, lemonade, espresso, so on, as long as you have the proper K-Cup in it.

If you brew hot cocoa, it is recommended running a cleaning brew with just water to make sure that the needles won’t clog up.

What kind of water should you use with Keurig 2.0?

Bottled or filtered water are recommended for all Keurig models, especially when your water comes with somewhat “off” taste due to chlorine or some other substances.

The optional water filter kit built in K350, K450 and K550 can only improve the water taste, not take out the mineral that can be collected inside the machines. Plus, softened water, hard water, reverse osmosis water and distilled water are all not recommended.

Keep in mind that no matter what type of water used, mineral deposits will be likely to build up inside the machine. So in order to make sure that your unit will always in good performance, descale your machine regularly to remove such deposits.


Operating the Keurig 2.0 is done through an easy-to-use touch screen. The power button is located in the bottom at the right corner of the touch screen. The button is illumintaed when the unit is on.


With the knowledge in product features and product parts above, we can summarize the good things of the system with some points as follow:

  • Keurig is one of the best single serve coffee maker manufacturers around
  • They brew quick, hot, and bold coffees
  • They make no mess when brewing and are comparatively easy to clean
  • They offer various coffee flavors, just by inserting a new K-cup, you will have a cup of coffee of your desired flavor
  • Rather than just coffee, they allow brewing a lot of other beverages which are all in variety of flavors.
  • You can use your own coffee with compatible Keurig 2.0 reusable K-Cups
  • You can brew extra bold coffee if you want
  • There are 8 to 10 brewing cup sizes for you to choose from
  • They work with Vue pack to produce larger cup of coffee with full flavor
  • You can make a carafe of up tp 4 single cups at the same time, using K-carafe packs
  • Carafe is programmable to make automatic brewing at pre-set time.
  • Although some types of water are recommended and some other types are not, the machines do not require any special water.
  • Auto on off feature is included.


There are some things in the machines that are not perfect, including:

  • They work with Vue packs for bigger cup sizes,  but some Vue packs haven’t been changed to work with Keurig 2.0.
  • Regular cleaning is required for perfect performance.

Customer service

The customer service is available 7 days a week. So if you run into any issues when using the machine, please contact by phone at working time or by email at any time. The manufacture staff will be always willing to help you with any performance issues.

To the issues on refunds or replacements, you are recommended contacting the sellers. In case of replacements, you should contact to ask for help from manufacturer first because they may suggest useful solution, sometimes no replacement is required.

Remember that warranty will be invalid if you disassemble the machine and fix the problems yourself. So be careful with any action.

What people have to say

I have found hundreds of Keurig 2.0 reviews from users. In general, most of the users are satisfied with these great brewing machines. On the other hand, there are also some users who are not very happy with the machine at some extents.

Many of those who support the products share that they like the models because they offer better coffee, especially the stronger coffee option which is hardly found in other coffee maker brands.

In addition, the machines are all easy to use, they can make their fresh cup of coffee after reading some instructions. The machines are also highly appreciated because they offer option to brew a carafe, which is especially convenient when you need to serve some people at the same time.

Actually, there are a lot of more reviews around Keurig 2.0 system, such as they offer users various coffee flavors, they allow various cup size options, the brewing process are fully programmed, but due to the limited time, I’d like to share some.

These reviews are not many, the information about product features, pros and cons above is enough for you to have a correct assessment about the product, I believe.

Tips for easier and better using

Here are some tips and suggestions that will be helpful for you to run the machine with ease and effectiveness. Reading the below information to discover:

  • Run the machine (without K-cups) with a cup of white vinegar diluted withwater in the reservoir to eliminate unwanted taste and smells
  • In case the travel mug doesn’t fit the machine well, set the machine on top of a box or a book to improve the distance between the counter and the dispenser nozzle.
  • Remove the K-Cup immediately after finishing brewing to prevent clogged needles.
  • Make a cleaning brew after brewing powdered-milk based K-Cups like hot cocoa.


To conclude, Keurig 2.0 is really a good brewing system. The models introduce an advanced brewing technology and basic brewing option to offer the best tasting coffee possible.

Most users, especially those who like rich bold coffee, agree that coffee brewed with a 2.0 is better than that brewed with the former K-cup coffee makers.

Also, the big water reservoirs means that less refill will be required and the possibility of carafe brewing means that you won’t have to make the second brewing for second serving.

And there are a lot of more great things that you have read through my honest and complete Keurig 2.0 review.

So if you are planning to invest in a new coffee maker, Keurig 2.0 is a worth consideration! Let’s check and have decision as soon as possible!
