Does it really brew ground coffee as well as K-Cups?

Yes. It has two formats: standard K-Cups and loose ground coffee, with a basket that holds up to 25 grams. That lets you use pods on busy mornings and your own beans when you want them.

How much coffee can I brew at once?

One cup per brew, in five sizes from 6 to 14 oz. There is no carafe option, so it suits single servings rather than filling a pot.

Will it fit under my kitchen cabinets?

It is 12.09 inches tall and 11.14 inches deep, so measure your clearance before buying. The width is only 5.51 inches, which helps on crowded counters.

What comes in the box?

The machine itself; the listing does not detail included accessories such as a ground coffee scoop or starter pods. Plan to supply your own K-Cups and ground coffee.

Does it have strength or temperature settings?

The listed specs cover brew sizes only, with no strength or temperature controls mentioned. If those matter to you, look at machines that advertise them.

How does it compare with a Keurig K-Duo?

The K-Duo brews both pods and a full carafe and offers more controls. The Quick Bite is single-cup only, narrower, and simpler, so it fits small spaces better but cannot fill a pot.
