In general, these 2.0 machines are the same. There are light differences in features.

For the most part, they work in the same way as the original Keurigs do-Pop in a K-cup and brew. But thanks to 2.0 brewing technology, you now can customize the coffee strength and pick out between 10 available sizes, from 4 to 30 ounces. And they are all able to brew a single cup within just minute.

The ones which come with 32-ounce carafe, together with other limited number of K-carafe packs allow you to brew up to 4 cups at once

time. And they take you a little longer time to brew, around 3 minutes in general.

Actually, there difference among these devides are more than those above, but the extent of this Keurig 2.0 review, I’m about to talk briefly.

Ok, so let’s take a closer look.

How Does Keurig 2.0 Work?

To give you the clearest look possible about the way these amazing products work, my review will approach the issue under some sub-issues as follow

The Amount of Coffee Every Serving Time

These powerful machine introduce up to 10 brew sizes. They are the 22, 26 and 30-ounce brews which all need the carafe.

The cup size when brewing from K-Cups are respectively 4,6,8 and 10 ounces. K-Carafe packs allow you to produce 22, 26 and 30 ounce carafes.

Types Of Coffee Used

If you want to make 4,6,8 and 10 ounce cups, consider K-Cups produced after 2014 with special encoding in the lids). They offer up to more than 250 flavors of coffee and some other beverages.

When you want larger cups sizes like 12, 14 and 16 ounce, check the Vue packs which are being made into the 2.0 brewers. Remember to pick the one with a large dot in the 9 o’clock position on the lid.

K-carafe packs are required when you want to brew small carafes of coffee. And now it offers 10 different flavors.

Type Of Coffee Produced

K-Cups offer a number of roasts and flavors, and can be found in a lot of coffee brands. Vue packs and Carafe packs offers a smaller selection.

Multi-Purpose Choices

In case no K-Cup or K-Carefe is included, the keurig coffee makers will generate hot water which is often used in making hot products, like hot chocolate, hot tea, so on. The Keurig 2.0 K550 comes with a button which dispenses hot water when you hold it down, meanwhile other items generate hot water when you brew without a coffee pod in place.

If K-cup is available, you can make hot chocolate, chai tea, iced tea and a lot of other hot and cold beverages. But remember to operate a cleansing brew after brewing hot cocoa so that the needles won’t clog up.


Actually, these items don’t require any coffer filter or water filter, but the elective water filter kit with charcoal filters is still included in models type Keurig K350/K360/K300, K450/K460/K400, and K550/K560/K500. The installation of the water filter like this will help to improve the flavor of off-tasting water, and finally give you better tasting coffee.



Keurig introduces both bottled and filtered water in every of its device. The elective water filter kit installed in the Keurig K350, K450 and K550 can not only improve the taste of the water, but also remove the minerals which are collected on the inside of the machine.

Please note that mineral deposits, which can make effects on brewing process, are likely to form in the device, with no concern about the kind of water used. In this case, desalting will help to remove these deposits and help to conserve interior part.

Hard water which contains much mineral makes the building up process faster, which means that you need to desalt the item more regularly, every 3 to 6 month.

These Keurig coffee makers  track the amount of liquid which go through the machine and deal with a “time to desalt” prompt, however you may need to do desalting more often if you are using hard water.

Brewing Time

In general, it takes around one minute for you to make a cup of coffee and around 3 minutes if you want to make a carafe.

Ongoing Cost

Actually, the conveniences and improvements of K-cups, Vue packs and K-cups pack make it a bit costly compared with the ground one. But the amount can be decreased when you purchase a large quantities and having a monthly auto-ship subscription.


The working process of this awesome machine are controlled by an easy-to-touch screen (The black and white one are for Keurig 2.0 K350, the colored one for Keurig 2.0 K450 and the larger colored one for Keurig 2.0 K550). The power button is at the bottom right corner of the screen. It only appears as long as the machine has been plugged in.

Coffee-making Process

Because there are 2 kinds of coffee- making kind, my review will deal with all of them.

To make a single cup of coffee:

  •   Put a mug in the drip tray
  •   Lift the lid, using the handle
  •   Place the chosen K-cup or Vue Pack in the holder.
  •   Close the lid by lowering the handle
  •   Choose the brew size and “strong”, if it is what you want. Or choose hot cocoa or some other, basing on what the instructions say)
  •   Press “brew” button

To make a carafe:

  •   Take out the drip tray and put the carafe under the nozzle
  •   Pick up a K-carafe pack and put it into the container, then close the lid
  •   Check whether the number in the circle on the lid is at 9 o’clock when being inserted or not
  •   Choose the size of brewing and press “brew” button.

Note that if you take out the carafe before the brewing process finish, it will stop and start again.

Yeah, this brewing process works for all packs: K-cup, Vue Pack or K-carafe. In case you want more flavors and settings, the final coffee might be in a pulsing, rather than the steady stream.

Ok, these are all I want to present about the working way of Keurig 2.0 (Models K350/K450/K550). And below are some reviews about its pros.

What Are The Pros?

Beside a lot of good reviews above, there are some not very good ones as follow:

  •   It doesn’t work with K-cup reusable coffee filters or the third party of the same kind for making ground coffee
  •   It doesn’t accommodate the large amount of some travel mugs

Tips From Users?

Here are some tips on how to use these keurig coffee makers properly from users.

  •   Use a cup of white vinegar throughout the item (don’t need to install a K-cup) and follow it with some water-only steps to eliminate possible lingering plastic taste and smell.
  •   In case your travel mug doesn’t work well, place the device on top of a book or box to make the counter higher compared with the dispenser nozzle.
  •   Minimize the needle clogging times by taking out the K-Cup once the brewing is finished.
  •   If you want to make some hacks, you can check youtube:

– To makes use of old K-cups, cut the top of the new machine and replace it to the position of the top of the old one

– Gain more sizes of cup, using a magnet.

– Note that the energy power saver auto-off mode dominates the auto-brew timer for carafes. If you find the auto-on at 6 am, you should adjust the Auto-off so that the item will turn off after 15 minutes of disuse, then ensure that the item is controleed to Auto-Brew a carafe before 6”15. If it is later, the machine won’t run because it turns itself off.

– The carafe is not able to keep coffee warm in a long time, but you can buy an insulated carafe separated ly.
