Why we love it

The K-Slim is the narrow Keurig with a real tank. At 4.76 inches wide it takes the same strip of counter as the K-Mini, but its 46oz removable reservoir brews about four cups before a refill, which is what a K-Mini can't do. It uses MultiStream brewing, makes 8, 10 or 12oz cups, takes a travel mug up to 7 inches with the drip tray out, and works with the My K-Cup reusable filter for your own ground coffee. It is 15.2 inches deep, so measure front to back as well as side to side.

Pros

  • 4.76 inches wide
  • 46oz removable tank, about four cups per fill
  • MultiStream brewing
  • Takes the My K-Cup filter for your own grounds
  • Travel-mug friendly

Cons

  • 15.2 inches deep
  • Three cup sizes, no smaller than 8oz
  • Cost per cup is far higher than ground coffee
