Taste Test

Just like any other Keurig K-pod coffee maker, the Keurig K155 Office Pro coffee maker serves up hot coffee quickly. But many coffee lovers critique the taste as being not upto scratch, as it would be with a drip coffee maker.

One good thing to say about the Keurig K155 Office Pro is that it is consistent and quick in serving up your morning cup of joe!

While the Keurig K155 Office Pro looks classy and has a price tag to fit, there’s no denying that it can do little more than brew K-cup coffee.

You cannot use coffee grounds or even other coffee pods for brewing with the Keurig K155.

However, you’ll be able to brew coffee, tea, and hot cocoa. Two sampler packs of cocoa and coffee that come along with your purchase are nice extras.

The Keurig K155 Office Pro coffee machine can brew in sizes of 4, 6, 8 or 10 ounce servings. Surprisingly, it doesn’t offer a 12 oz serve as the almost similar Keurig K150 model.

Enjoy Delicious, Tasty Coffee – Fast!

Your coffee will be ready, hot and steaming in just a minute or less.

You won’t be able to make espresso shots or other milky specialty coffees using the Keurig K155 Office Pro though.

There are limited customization options, and you cannot make iced coffee or even adjust the brew strength too much.

The large 90-ounce water reservoir spares you the trouble of frequent refilling.

Brew Speed

The Keurig K155 Office Pro only takes a minute to warm up when you switch on the machine. Then you select a brew with a tap on the touchscreen. In just another minute, your coffee is ready.

Every additional cup brews even faster, averaging just 30 seconds!

Brew Temperature

For optimal extraction of flavor, coffee should be brewed between 195 to 205F. Unfortunately, the Keurig K155 Office Pro often doesn’t deliver this temperature even if there are settings to adjust it. Maybe the controls aren’t very effective.


Keurig K155 Office Pro coffee maker operates at an impressive energy saving. Even when it runs for an hour, you’ll use just around 125 kWh.

The machine is also really quiet when brewing. The highest noise level is around 65 decibels, which is barely noticeable.

Coffee Bar At Home

The Keurig K155 Office Pro is among the most attractive Keurig coffee makers, with an elegant minimalist design.

A shiny silver color frames a large, bright LCD touchscreen display, lending a touch of class to this commercial coffee machine that’s only a little shorter than the Keurig K-Classic model.

Although big, the Keurig K155 Office Pro is lean for a commercial coffee brewer.

A silver plastic finish means it fits in nicely with home or office decor, with a gleaming drip tray and sleek contour that’s posh and stylish.

The machine is rather heavy at 20 pounds, which makes it inconvenient to keep moving around often.

Water Reservoir

A large water tank with 90 oz capacity means you won’t have to refill it too often. You could remove the reservoir and fill it from the sink, or use a pitcher to pour water into the opening at its top.

It would have been nice to have a direct connection to a water pipe outlet, like the Keurig K150 model offers.

Ease of Use

The Keurig K155 Office Pro is an easy to use machine. There are just 3 clearly labelled buttons to control your brew.

  • One is the ‘Brew’ button which lets you select the serving size.
  • Another is labelled ‘Coffee’ and starts the brewer.
  • The third called ‘Water’ is when you want to serve hot water for tea or cocoa.

The LCD display screen is large and easy to read. All options are picked right on the touchscreen.

To start brewing, you simply insert a K-cup into the pod compartment, close the latch and choose your brew size.

Interactive LCD Touchscreen

The color display lets you adjust brew temperature in 1 F increments, between 188 and 198 F.

(Only the Keurig K-Elite and Keurig K-Supreme models offer temperature setting adjustments.)

You can program the coffeemaker to turn on at a certain time so you’ll wake up to the delicious aroma of fresh brewing coffee.

All these options as well as adjusting the time on a clock in the display can be done using an interactive touchscreen. Just tap the screen and follow the prompts.
