Stainless Steel Reusable K Cups Compatible with Ninja Coffee Maker,Upgrade2 Pack K Cups Reusable Coffee Pods,Permanent Coffee Filters Fit Ninja CFP201 CFP300 CFP301 CFP305 CFP307 CFP400 (2Pack)

I have two of these to use with my ninja dual Brew pro coffee maker. I load them with 10 to 11 g of ground coffee and use the Keurig adapter. They work great! If you use a coarser grind, you will not have sediment in your cup. There is no plastic waste like there is with a K-cups. It also is much less expensive to use this product than it is using preloaded K-cups when brewing a single cup of coffee.

It works amazing, just don’t do what I did the first time I used it and open the top and grab it lol it holds a lot of heat

Love the reusesble K cup . Only problem it spits coffee a bit onto the heating unit. But it’s doable.

Great idea, seems to work good, however can be a bit messy if you don't use it completely correct. When you wake up at 4 am, this may be a problem. However good for the environment, easy to wash off and reuse time after time. Best thing is you can use your favorite coffee that often doesn't come in a K-cup or the like.

I love these, they fit perfect and the stainless steel, not plastic is great.

These stainless steel reusable K-Cups are a perfect fit for my Ninja coffee maker. They work great — no leaks, no mess, and the coffee brews just as strong and smooth as with the disposable pods.They’re also super easy to clean, which makes them convenient for daily use. Plus, I love that they’re eco-friendly and save money in the long run.If you’re looking for a reliable, reusable K-Cup option, this is definitely worth it!

I've had it for a couple months now and it's been working perfectly

Well going the durability non plastic container is amazing I’m not putting any hazardous chemicals in my body this way. Easy to remove, easy to clean. Save the world by using these. Do your part.
