Very nice k-cups in stainless steel
I didn’t read closely enough that these k-cups are just for the ninja machines, and not for Keurig. That is my fault. I originally saw ‘k-cup’ when looking at these and didn’t realize this term is also used for other coffee makers. That said, I cannot use these reusable coffee pods in the Keurig machine that I own. Since there is no hole in the middle, the cups will not fit, so don’t make the mistake I did when looking into ordering these. I do like the feel of these cups, they are solid but not too thick, think ‘just right’. The materials used appear to be quality. I like that the holes for the coffee are a bit smaller and covered better than another set I got for Keurig, a similar shape and material but they had holes that were too big and this allowed for a lot of grounds to be brewed into my coffee cup, which is a definite ‘pet peeve’ of mine. I hate coffee grounds in my coffee. So I was excited to try them out to see if this better looking coverage would brew a nice cup of coffee but keep the grounds out of the freshly made coffee. However, since I’m unable to use these, I can’t report if it does or not, but the maker seems to have thought about the grounds problem, and the holes appear nicely engineered, so I hope if you get these k-cup reusable pods for your ninja machine, that they make nice cups of coffee without any grounds.

Do not over fill
Work great. My boyfriend loved it.. the coffee was so my better than the k cups.

A terrific product that works exactly as I hoped
These reusable pods are a terrific product. They fit our Ninja CFP301 coffeemaker perfectly. To be able to close the coffeemaker and brew, the pod lid’s holes must line up with the coffeemaker’s ‘injectors.’ That’s quite easy to do, using the markings on the pod lid. The lid fits tight into the pod after loading it with coffee, and the coffeemaker closes easily. I use paper liners in my reusable pods. As a test, I brewed several cups without the liners. As expected, brewing without the liner means tapping the pod against the trash can to empty it–several hard taps, in fact. Then a good rinse and wash with dish soap to remove the coffee oils from the pod. With a paper liner, emptying is a breeze and requires just a quick rinse after tossing the grounds. I did notice that without the paper liner, the pod’s steel mesh let some sediment through, which I then found on the bottom of my cup after drinking the coffee. It wasn’t much and wouldn’t bother me, but it’s a non-issue with a paper liner. One last thought: The pods’ package warns that the pod will be hot after brewing, and I wondered if that would mean leaving it to cool before emptying or brewing with a second pod. But I found I could comfortably handle the pod immediately after brewing stopped, using my bare fingers. That said, everyone’s heat tolerance probably differs, but I suspect that for most, it would take just a short minute or so to cool the steel pod for comfortable emptying. After several years of using plastic pods, I was delighted to find this stainless steel version. It meets my needs perfectly.
