Differences Between: Keurig K15 vs K55

Keurig K15 vs K55

Performance – Big Edge: K55

The Keurig K55 does a better job at brewing coffee. It’s vastly superior as an everyday versatile machine that lets you customize your own cups of coffee in the morning. The removable 48-ounce reservoir even allows for satisfying everyone’s morning needs, but the Keurig K15 requires being constantly filled with water and doesn’t always produce hot enough coffee.

Price – Edge: K15

The K15 isn’t quite as affordable as a ham sandwich, but in terms of Keurig pricing, it might as well be. It’s a good idea to hedge on the issue of price because on any given day price might change.

If the two are separated by only a few bucks, the advantage could switch. That’s not the case here. We don’t see any normal circumstances where the K55 costs less than the K15. We give our edge in this case not just on raw dollars, but in terms of value.

The K15 has a much lower price, but it sacrifices a lot to get it. What would be a big edge is in fact just a regular old edge.

Durability – Big Edge: K55

One of the things the K15 sacrificed to get it down to its price was durability. The K55 has its own lingering questions about its operational life, but they’re nothing like the K15.

The K15 is just not designed for the kind of constant, everyday use you can put a K55 through. The K15 is fine for brewing one cup a day. The K55 is fine to brew a few cups every day.

Design – Slight Edge: K55

If you don’t have a lot of space for a coffee maker, the K15 is probably your best bet. It’s designed to be as small and unobtrusive as possible so it’ll save you space without sacrificing quality.

The K55 has one really great feature that sets it apart from other models: its 48-ounce water reservoir that allows you to brew several cups before needing to refill it (it also lets some control over the strength of your brew). We like how efficient the K15 is but we really like what this model offers in terms of customization options!

Keurig K15 vs K55: Which One is Right for You?

There is no right to persuade you that one of these two machines is perfect for you. For sure, it does but only in particular cases. If you are a single person, and the flat you are living in is too small – then take a look at Keurig K15. However, if you value your time and want to be free to choose from the variety of options – then check out the Keurig K55.


The K15 is a great Keurig that replaces drip coffee makers for those in the market. The downside to this model, however, is its lack of versatility and quality–id est it sacrifices too much to get its price down. Unless your needs drive you to something small and really affordable, we’d suggest spending just a little more on the K55 instead.

We liked the Keurig K55 more than the Keurig K15. However, we should make it clear that this does not mean we hate the latter model. What’s great about it is its ability to brew coffee for someone with limited space or a tight budget; and you can use both models in many Keurig Classic machines as well. Having said that, if you are looking for an everyday brewing machine, such as one which performs better and lasts longer than others-choose the Keurig K55!

Frequently Asked Questions

What is the difference between the different Keurig models?

There are just two major differences between the B40/K40/K50 brewers and the K-Classic: The K-Classic’s slightly expanded brew sizes (6, 8, and 10 oz) Its upgraded brewing system that ensures you’re brewing with Keurig’s latest and greatest technology for hotter, stronger cups.

Why was the Keurig 2.0 discontinued?

The problem with Keurig 2.0 is with the machine’s DRM (Digital Rights Management) system. DRM makes it so Keurig 2.0 machines only accept official, and more expensive, Keurig K-Cups that are one-time use only. The consumer backlash to this decision was more than the company anticipated.

Is Keurig K55 discontinued?

The Keurig K55 is currently discontinued and replaced by the K-Classic, which offers many of the same features. The main difference between the two products is that there are no Strength Control or Temp Control on this model. You also have Auto-On/Off functionality and a removable drip tray to easily clean it out!
