Stainless Steel Reusable K Cups Compatible with Ninja Coffee Maker, K Cup Reusable Coffee Pods,Reusable Coffee Filters for Ninja CFP201 CFP 300 CFP305 CFP400 Not Fit 1 Hole and 5 Hole (1Pack)

I'm so glad I found this! It works perfectly with my Ninjua coffee maker and saves me a lot of money! I'm the only one in my house who drinks coffee, so I was buying single-serve pods all the time. It's easy to clean, and I have had no issues with quality. I am careful not to overfill, though, because the grounds will leak out.

The stainless steel reusable K-Cups are a must have addition for the Ninja coffee maker. They are very easy to use, and will save a fortune over using k cups only. I found the Ninja coffee maker to be very picky about which K cups worked well, with the cheaper ones leaving a lot of grounds in the coffee maker. These reusable cups don’t allow any of the grounds to escape if used properly. Make sure that the notch is facing forward and the lid is on light when placing in the machine (so the three ports line up correctly). They seal tight when closing the machine lid, and the brew speed is similar to regular K cups. After brewing, wait a couple of minutes before removing from the machine as they get pretty hot. I also recommend setting the machine to “closed” to avoid any excess dripping when removing the reusable cups. The only drawback is the need to clean them out every time, but this is why I keep regular K cups for the times when I am in a big rush. They are dishwasher safe and come out like new every time. For some reason it was cheaper to buy them separately rather than a two pack on Amazon, but they are still a great value for the money.

I have no idea why if you look at the summary of the reviews it says that this item is frequently sent back. I don’t know why. It is metal. It is sturdy and it works. I have a ninja. This works every day not a single leak. There is nothing about it That sprayed out of the ninja or goes all over the place. Nothing anyone has said has happened to me. It is metal it doesn’t bend it doesn’t break. It works beautifully. No plastic has a magnet basically so it can stick itself together and stay held together. It’s NOT a STRONG magnet, but it does it need to be because you just put it on top and leave it there until the next day and by the way because it’s silver and not black it’s much easier to spot gor me with that yellow mark .

These filters have a fatal design flaw: they have a screen all around the filter from top to bottom, something the K-pods do not have. As we know from grade school, water uses the path of least resistance so, instead of being forced though the coffee grinds all the way to the bottom, as it does in the K-pods, the water just squirts out through the side screen. Hence, you can never get a good, satisfying, strong cup of coffee! It's always on the weak side, no matter what. And, if you overfill the filter, you have another problem. The grounds clogg the nozzles and you have a mess on your hands. Good idea, poor design.

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.

Perfect fit and works with my Ninja Dual Bre

Perfect fit for my ninja coffee maker.

The lid doesn't stay tight enough and I am constantly getting coffee grounds in my coffee. That being said, it is easy to clean because the lid comes completely off. It works for what it is, but I will be looking for other options.

I had bad experiences with the early plastic re-usable K-Cups back when I was using a Keurig brand brewer. They leaked and fit poorly in the machine. They were also a pain to clean since the coffee got stuck between the plastic frame and the metal mesh. This stainless steel cup in the Ninja brewer works perfectly. The silicone seal keeps the coffee grounds in the cup and the coffee comes out tasting great. In fact, it tastes better and smoother than when I use the same coffee with a drip filter. It also tastes better than regular K-Cups. Cleaning is a cinch. The grounds have nowhere to get stuck. It's also solidly made, so it will last at least as long as your coffee maker. Given the excessive price of K-Cups, this little gadget will pay for itself in no time.

Perfectly fit my Ninja coffee maker. Very pleased with this product. Much more economical than purchasing disposable refill cups.

Water leaks out the bottom and sides, so the coffee spews everywhere and makes a huge mess

Wonderful product, perfect size for my Ninja and makes great coffee

I was about to come here and review it with 1 star, but the real issue was that I didn't read the whole instructions on how to use it. It works perfectly! No more pods in my house!! :D
