Keurig K55 Review – Is It Worth the MONEY? (2019)

Keurig K-Classic Coffee Maker K-Cup Pod, Single Serve, Programmable Black

The Keurig K55 is a basic one cup machine that will give you a consistent cup of coffee with no fuss. It has few bells or whistles, but unlike flashier models of Keurig you’re not restricted to K-Cups. And as well as using compatible pods, the refillable capsule lets you grind your own coffee if you prefer.

While it’s super-easy to use, your K55 will need a bit of maintenance to keep it in tip-top condition. That means not just descaling, but unclogging the needles that pierce the pods. If you think that’s a small price to pay for decent coffee that’s ready in seconds, this could be the machine for you.


Not one for gourmet coffee lovers, but produces a decent cup every time


Compares well to fancier single cup machines

Couldn’t be simpler. Loses half a point for needing to clean the needle.

What others are saying about keurig k55 coffee maker

A hunt around the intranet found plenty of people who were devoted to their Keurigs. Its simplicity and reliable coffee seem to be the main selling points.

This YouTube review provides a good overview of all its features and benefits.

Keurig K55 Review

If your household is anything like mine in the mornings, you’ll need a coffee maker that’s easy to use.

When everyone’s rushing around getting ready for work and school, a single cup machine comes into its own. Just pop in a pod, press a button, and seconds later you’ve got a warm cup of Joe. Perfect.

It’s this convenience that has made these machines hugely popular – and the manufacturers have responded with a multitude of models. So how do you know which one to choose?

Things to consider before buying a single cup coffee maker

First of all, ask yourself what you’re looking for from your coffee-making experience.

If the answer is a cup of coffee that tastes exactly how you expect it to, single cup machines are great. Just choose your favorite pod and they’ll give you the same coffee every time.

And if you don’t want to spend time in the kitchen, they’re a good option. Fast and efficient, they only heat as much water as you need. They’re usually pretty easy to clean too.

All in all, they’ll give you a reliable brew with minimal effort. What’s not to like?

Well, for some people they can be a bit utilitarian. Yes, you get consistent coffee – but there’s very little opportunity to make it your own way. If you get a kick out of testing out different brew ratios or grind sizes, a single cup machine is unlikely to be for you.

And if you enjoy sharing a pot of coffee amongst the family, go for a drip brewer instead. Alternatively, one or two machines out there can brew either a carafe or a single cup. They’re a great choice if one person is sticking to decaf.

Performance of ​keurig® k55 coffee brewing system

Keurig K-Classic Coffee Maker K-Cup Pod, Single Serve, Programmable Black

The K55 is also known as “the Classic”. That name tells you pretty much everything you need to know about how Keurig are marketing this model.

Essentially, it’s a pretty basic machine. It doesn’t have any of the add-ons of more expensive options.

There’s no “strong brew” setting, as with the K-Select or K-Elite. And it doesn’t have a special setting for iced coffee, another of the Elite’s features.  There’s no color screen or temperature controls. But it does its job at an affordable price.

It replaced the earlier K50, and while the two machines look similar the K55 has a smarter edge. It’s also smaller and lighter, despite having the same size water reservoir. The buttons are more responsive too.

All in all, the K55 is a modest upgrade of the K50. Keurig claims they’ve improved the engineering and it’s less prone to faults. And the basic design certainly means there’s not much to go wrong.

And while it may not have as many gizmos as other machines, there are still some interesting features. So if you’re looking for a solid machine with a decent brand reputation, the K55 is worth considering.

Features and benefits


Compact styling

For an inexpensive machine, the K55 looks pretty good. It’s available in either black or red, and its smooth curves and silver trim give it a touch of style.

Keurig offer may more compact options – the K-250 or K-14 Mini - but the K55 is still fairly trim. At 13 inches long, 15 inches wide and 15 inches high it won’t take up a lot of space on your countertop.

This is strictly a domestic machine, so there’s no option to plumb it into your mains water supply. On the plus side, that means it can be positioned pretty much anywhere.

Its lower height also means it will fit neatly under wall cabinets. If you’re struggling with space, that could make it a better option than many drip brewers.

Fast brewing

The major advantage of the K55 is its super-fast and easy brewing.

When you’re ready for your coffee, simply raise the handle, insert a K-cup and lower the handle again. That action inserts a needle into the top and bottom of the K-cup. Then all that’s left to do is to press the brew button (1).

The machine will respond by sucking up water from the reservoir and heating it up. The water then passes through the needle, into the coffee grounds, and out into your cup. It’s a beautifully simple process and it’s all done in less than a minute.

There’s virtually no recovery time between cups, making it great for larger households. With some drip brewers, later risers may find they’re left with coffee dregs burning on a hot plate. With the K55, everyone gets a fresh cup with no need to wait around.

Three serving options

There aren’t as many options to choose from as some machines. Nevertheless, you can choose between 6, 8 and 10 ounce serving sizes.

Those who want a bigger cup of coffee shouldn’t be tempted to press “brew” for a second time. That will simply dispense more water through the used coffee grounds. You’ll be left with an over-extracted drink and a bitter flavor.

Instead, replace the pod before repeating the process. You’ll get through your store of K-Cups more quickly, but you’ll avoid a watery drink and unpleasant taste.

One other issue to be aware of: the cup stand isn’t adjustable. The limited serving sizes available here, however, make this less of a problem. Reassuringly, we haven’t seen any reports of splashed countertops.


Temperature control – or not

The K55 lacks one key feature of more expensive single cup machines: temperature control.

The failure to get a properly hot cup of coffee is a recurring complaint with this kind of coffee maker. More advanced models seek to deal with this by providing different options – usual variations on the hot, extra hot theme.

So with no ability to change the temperature, does the K55 doom you to lukewarm coffee?

Not necessarily. To start with, how hot is “hot enough” is very much a matter of personal taste. You may find the brewing temperature perfectly adequate for your needs.

But if you like your coffee really hot, there are things you can do to boost the temperature. Firstly, always prime the brewer to warm the internal reservoir. That will avoid heat being lost warming the inside of the machine when you brew your coffee.

Secondly, use the hot water from priming your machine to rinse your cup. A warm cup will keep your coffee hotter for longer.

Of course, this does add a bit of time to your brewing process. But it’s pretty effective – and less expensive than buying a brewer with temperature control.

Able to dispense different beverages

The K55 is very forgiving when it comes to which pods it will work with. You can use any K-compatible pod except the newer ones designed for machines with larger serving sizes.

You can also purchase a refillable pod for your own ground coffee. If you love a particular coffee bean, why not grind your own? And because they’re reusable, these pods are much kinder to the environment. Unfortunately, standard K-Cups are still not widely recycled.

Unlike the more expensive Nespresso single serve machines, you’re not restricted to coffee either. The K55 will take all kinds of K-Cup – and that includes the cocoa and soup options now available.

And because the machine will dispense hot water when there’s no K-cup, you can be more creative. Make tea the right way by steeping the tea bag in hot water, or use it for your oatmeal.

The restricted serving sizes may mean you’re not ready to replace your kettle altogether. Even so, the K55 offers plenty of flexibility.

Auto off

A handy feature for those hectic workday mornings is the auto off function. The K55 will switch off its power after two hours without use. So if you’ve been distracted with other things, you won’t need to worry about it using electricity while you’re out.

If you wanted to be picky, you could complain that you’re stuck with the two hour period. There’s no way of changing it as with other machines. But it’s a simple solution with no programming required.

One arguably more serious limitation is that there’s no auto on function. For those people who like to fall out of bed knowing their coffee maker is ready to go, that will be a problem.

But even if you prime your machine before you brew, your coffee will be ready in under two minutes. You might not be able to wake to those lovely aromas, but you won’t be waiting long.

48 ounce water tank

The reservoir in the K55 might not be the biggest, but it’s worth remembering the serving sizes aren’t huge either. You’ll be able to get more than six cups before having to refill it.

When it’s time to refill, the reservoir slides out from the body of the machine easily enough. Its tall, narrow shape means it fits easily into one hand. And an advantage of its more modest size is that it won’t be too heavy to carry easily when it’s full.

Another handy accessory is the Keurig water filter holder. You can often buy this as part of a package with the K55, and sometimes water filter tablets are included too.

Using the filter will avoid any unwanted flavors from your tap water ending up in your coffee. And if you’re planning to dispense hot water for soup, you’ll really appreciate the purer taste.

As an added advantage, the filter will also increase the length of time you can go without descaling your machine. And it can make a big difference to its lifespan.

Automatic descaling alert

Whether you use filtered water or not, you won’t be able to get away without descaling forever. It’s a task that usually has to be carried out every few months. The precise period will vary depending on how heavily you use your machine.

Fortunately, you don’t need to do any tricky calculations involving water hardness and cups per day. The K55 has an indicator light that lights up when the machine needs to be descaled.

It’s a pretty simple task and some packages will include a bottle or two of descaling solution alongside the machine. Descale as soon as you see that indicator light, and you’ll be rewarded with a longer life for your machine.

If you’re after a basic single cup machine, the Aicok single serve coffee maker is worth a look. it’s an even more budget-friendly option.

Not surprisingly for a machine at this budget, it has its limitations. The water reservoir will only hold 12 ounces, and there’s no option to change the serving size. Its bijou dimensions also mean that it will only take a cup a maximum of 5 ½ inches high.

But if you’re looking to spend as little as possible on a machine, the Aicok is worth a look. And its two year warranty is twice the length of that offered by Keurig.

#2 keurig k55 vs ​Hamilton Beach FlexBrew 49975 Single Serve Coffee Maker 

This Hamilton Beach model is a direct competitor to the Keurig K55. The three serving sizes and 40 ounce water reservoir look very familiar.

There are, though, some nice extras.

The largest serving is 14 ounces rather than 10, and a refillable pod is included with the machine. There’s also an adjustable cup rest which doubles as a storage compartment. And unlike the K-55, there are two brew strengths to choose from.
