6-Pack Reusable Refillable Single K-cup Compatible with Keurig 1.0 Brewers – KozyCircle Coffee Replacement Mesh Filter Pods with Lids – Perfect Gift for Coffee Lovers

These little cups work really good and seem to be well built. The tops sometimes have a tendency to pop open, this only appears to happen if you get a little coffee in or around the seat. They are held closed by a friction fit between the top and filter bowl, so just make sure the seating area is clear before closing the lid and you should be good to go. A snap top would be a nice improvement to the cup design. The stainless steel filter material is nice, I've had other cups that used a nylon mesh and they are pretty fragile. I'd buy these again, but it will probably be a while before I need to.

I rarely take time to write reviews unless a product is amazing, fits unusually large or small, or is subpar.There is a top piece that slips off inexplicably, and seems to have no function that removing it would be useful for. However, without it, numerous coffee grounds will be in the bottom of your cup. Maybe half a teaspoon. Gross.The company even emailed me to "make sure" the top piece is always in. But if it falls out without me removing it I'm not sure how I'm supposed to do that well.Dishwasher safe except that piece falls out and must go down the drain because in my set of 6, 4 are missing the top piece and are rendered pretty useless.Buy the name brand. Drink coffee not grounds.Please note I did always make sure there were no grounds under the lid and it was clicked closed securely. I did not overfill the cup. Though I don't drink coffee that strong and I liked it best filled right to the top. I made sure I slid the O ring on the top part of my keurig all the way down to touch the cup and get a proper seal. These adjustments made it marginally better, but with missing top pieces grounds were always always in my cup.Also, make sure you line up the plastic ridges on the bottom of the keurig where the bottom price would normally pierce a plastic k cup, so it *doesnt* pierce the mesh.

I saw a strange issues with these reusable K-cup filter pods. As my coffee was being dispensed, I saw that there were water drips coming from my coffee maker. Since I had purchased a second set of pods from a different vendor I used one of those with no water drips. Upon further investigation I discovered the insert in the top of the lid in these Kozy Cup pods was loose causing water to come out of the top the these pods when under pressure. My solution instead of returning them was to super glue the inserts in place. After the glue has stopped out gassing I'll give them a try. These purple ones worked perfectly: GoodCups® ASIN:B01KJUC2JC (Set of 6)

Although the Keurig K140 is marketed as a commercial machine, this refillable cup fits perfectly in the replacement k-cup holder we had to order. Our original k-cup holder's needle was broken due to user error.The original k-cup holder that came with the K140 has an ever so slightly slimmer inner diameter which causes these to be almost too tight of a fit (though they work). The replacement (labeled "revision B") has the same outside diameter but the wall of the holder is slightly thinner giving the replacement a slightly larger inner diameter.The revision B of the k-cup holder and these refillable cups fit perfectly. The hollowed out bottom means that you won't risk damaging the k-cup holder's needle which is used to puncture k-cups. Also, you don't have to align the refillable cup in a certain way: it easily rotates 360° inside the k-cup holder making it virtually idiot proof.Would highly recommend.

I used one of these K-cups with a Keurig model B44. It seemed to work well on the first and second uses. However, during the next two uses, water started coming out around the edges of the brew chamber as well as through the center hole, resulting in a mess. I thought I used too much ground coffee, so I tried using one tablespoon. Same result. I used my daughter's Ekobrew with one tablespoon of ground coffee for the next brew, and the water came through the brew chamber with no leaks. This appears to be an issue with these K-cups, at least with this particular Keurig model. Very disappointing. Then again, I should have paid attention to the description...to be used with Keurig 1.0 models. Now I know.

Easy to use. Not too bad to clean. Coffee is really weak so if you like weak coffee, this is the way to go. I filled it full and used the small cup setting and it was a little better. Strength of coffee really compromised.

These are great to use for making tea, or coffee in your Keurig Flavored teas are my favorite. You can use these for using coffee in the can, as it is less expensive than the cups.

work well - the liners are a tiny bit large so sometimes I need to fold the part that is over theclasp.
