GoodCups 4 Reusable K Cups for Keurig K Supreme, K Supreme Plus and K Slim with Multistream Technology - 4 Black Refillable Kcups Coffee Filters for Keurig Coffee Makers

--These GoodCups reusable cups fit my new KSlim machine and work well.--I had an old Senseo single-cup machine which finally gave out and I was left with lots of flat pods. These cups hold the content of a whole Senseo pod, so there's easy transfer from flat pod to reusable Kcup.--Each cup has two side flanges which fit perfectly into the hollows in the Kcup holder, so that the top holes are oriented to receive the five sharp points of the KSlim with no problem. The front of the cup is also clearly marked with the word "front."--The coffee brews neatly and tastes great.--I love that there are four cups in the reasonably priced box. I can preload a few cups in the evening so I don't have to do in it the morning--before I've had my coffee. :-)

Bought a Keurig reusable pod with my machine and the sediment left in the cup was unbearable. Looked for filters that would fit it and had no luck. Bought these pods and Pro Mael Disposable Coffee Filters 360 Count Coffee Filter Paper for Keurig Brewers Single Serve 1.0 and 2.0 Use with All Brands K Cup Filter (White)......., problem solved. Easy to fill, load (Front clearly labelled on the cover) and clean. Perfect coffee, economically.

These are easy to clean and seem to allow good flow. My previous one got so clogged up that it wasn't working well. It didn't have enough open space due to the plastic structure. I don't think these will have the same problem. The lid may eventually break off but I think it will last long enough to be worth it.

These refillable pods are so simple to use (favor them over the actual Keurig refillable pods) and they brew fast and a full robust coffee! Absolute game changer to buying expensive pods and constantly searching for pods on sale.We bought 8, keep them filled and ready to go as we are avid coffee drinkers!!!Cheers and happy brewing.

Works well but coffee grounds spill out of the large holes on the top
