Cafe Flow Stainless Steel Reusable K Cup, 2-Pk by Perfect Pod - Refillable Capsule Cup Metal Coffee Filter for Keurig 1.0, Keurig 2.0, K-Duo, K-Mini and Select Models (See Full Compatibility Chart)

Fits my Keurig K Cafe single serve perfectly. Taste is so good, much better than the plastic reusable cups I use to use. Can’t speak to longevity of the hinged top but I really like the design. I use paper filters for easy clean up and the lid still closes with the paper filters.

Product works well, fits the coffee maker and easy to clean. If

EDIT: One year review!We bought six of these a year ago, when they were one of the first on the market. I thought I’d update my original review after a year of heavy use!One year review:They’ve performed flawlessly… no failures whatsoever on six of these. We are getting amazing results using a fine grind. Here are some tips:– first off, if you like a medium-light roast and have an Aldi store nearby (Aldi is a German-based company that provides a scaled down Costco-type store with amazing products and prices), you should try their whole bean coffee – it’s amazing and only $6.49 for 12 oz). Fair trade, single origin, organic… an astonishing bargain (I have no affiliation with Aldi).– these are easy to clean if you clean them while the grounds are still wet. We just turn them upside down and tap them down in the sink… the result is a little pyramid of coffee. Then we use the sprayer of the sink to flush the grounds out – just stick it in the cup and pull the trigger. If a grain is stuck, shoot it from the outside. Super fast to flush and clean… we don’t even wash them in the dishwasher any more, but they do fine on the top rack.– you have to fill the cup all the way above the top holes. I fill the cup, tap it down vigorously to compress the grounds (this is important) and then top it off and tap it again. Compressing the grounds this way slows the pour and is a key to getting rich, strong coffee (read the old review below to see what I do that further slows the pour).– a year of tapping to fill and knocking them in the sink to clean, and they are like new… no damage whatsoever. These have been such a great purchase, and the fresh ground coffee we are enjoying is far, far better than any commercial k-cup you can buy. You probably won’t save money, but you’ll have great coffee and will avoid the plastic waste (read my edited original review below for the reasoning here).– all in all, a great purchase that we use daily!Original (edited) review 1/6/21… at the time, these were one of the very first stainless steel cups on the market. Here's my initial review from a year ago:Just received our order and tried them out. Here are my my initial impressions (I’ll update this as I tinker with them):- they seem to be well made, but will report if they fail in any way. I don’t see them as cheap or flimsy. Delicate perhaps, but I expect they’ll last with a little care. I inspected the build quality — particularly the rather intricate inner, small box piece (that makes way for the bottom-piercing part... K-cups are pierced both top and bottom when you close the lid). To my amazement, all seams are soldered tightly and beautifully. I made my way through grad school as a hand-crafted jeweler, and this work impresses me.- they fit perfectly in our machine (don’t remember the model, but it’s the one that does lattés). The cups doesn’t move around… the hinge keeps them from rotating.- it takes a little self-training to pull up on the non-hinged side for filling and cleaning, and to insert them properly. But there is a different shape to the “wings” of the top – the non-hinged side has angles. Even so, I found myself trying to open them from the other side, so I have to train myself to be mindful of those angles (after a year I still pull on the wrong side so the problem clearly ISN'T these cups... maybe my wife is right and I’m an idiot :). The angles also help to put it in correctly – always keep the angled side to the right (there’s an arrow, but as other mentioned it’s really hard to see).- water flows through more quickly than a k-cup (I used coffee from existing pods to test as we wait for our grinder to arrive). The coffee is weaker because of this, but still drinkable [note: we are now enjoying freshly ground strong coffee]. K-cups have a filter inside which keeps residue from your cup and slows down the pour. A fresh grind should help the strength (and taste) of the coffee, but I’ll have to find a way to slow the pour. As I watch it, I see the water run clear fairly quickly. Filters are available, but I’d like to keep it simple and avoid more waste, so I’m going to see if I can find another solution.- a small bit of fine residue is left in the mug… again because of the lack of filter material. This doesn’t bother me but it does my wife, so I’ll have to find a solution for this as well.- as others have mentioned, the large hole in the top allows grounds to spill easily if the pod is shaken or falls sideways. It will also likely allow the coffee to go stale faster if you load several up ahead of time. We are hurried in the morning, which is why we use a Keurig in the first place, and I'll be loading some the night before so I’ll be thinking about a solution here as well.- the lid has a tiny o-ring that seals the top. Not sure why, since the large hole will allow leaks if that is going to happen (it didn’t at all in our first tests). The o-ring does keep the lid closed, so maybe that’s the main purpose.All in all, these seem like a good solution and a quality product – with the modifications described below, we are getting very good coffee with fresh-ground beans. I like stainless steel rather than plastic, and it makes them easier to clean than the screens found in plastic versions. The actual coffee cost per year is slightly lower for ground beans [edit: wrong – see below], but more importantly we avoid throwing 1440 used plastic k-cups in the garbage each year. We are committed to reducing our plastic usage, and k-cups are a problem.EDITS:Six of these fit snugly into a square 1.8ltr/5 cup Snap Ware container, and that should keep them upright and avoid excess drying of the grounds overnight (see pic). I grind the coffee and set up the cups every night, in preparation for the next day (I do my oatmeal at the same time). Freshness and spilling problem solved with a decent airtight container.Our grinder arrived, and after experimentation, the finest espresso grind seems to give the best results. That also seemed to be the grind I found when I “dissected” a k-cup. One nice surprise is that almost no grounds or sediment was left in the cup with my fresh grind, even without filters. The k-cup coffee I initially used must have had a fair amount of grinding dust in it, because quite a bit of sediment was found in those test cups.I found that tapping these stainless pods down as you fill them helps keep the coffee well packed, which is important for slowing the pour. I fill the pods to just above the holes on the sides – packing and filling the pod above the top holes is vital for strong coffee!SLOWING THE POUR! This is a bit of a challenge… even with fresh espresso-ground coffee, the coffee is a tad weak because the flow is too fast. I’ve found that there are actually far too many holes in this stainless steel pod… I eventually got perfect results by blocking off ALL the holes on the sides! This slows the pour and makes the coffee much stronger and far better tasting (a bit of crema actually develops in your cup). After blocking all the holes on the sides, there’s no spillover of water on top – the bottom holes alone are enough to allow the water through at a safe rate. If you think about it, all the water in a regular K-cup has to flow out of the small hole that is punctured in the bottom when you close the lid – these stainless pods simply allow water to flow through too quickly.So how to fix this? I used shipping tape to experiment, but this clearly isn’t a permanent solution. The answer finally came to me: I can slip the stainless pod inside a plastic pod with the bottom cut off. We happened to have some plastic Melitta JavaJig pods from earlier tests – the JavaJig pods are plastic and use a paper filter and have an open bottom. After cutting out the fins in the bottom of the plastic cup (I used a Dremel), they slip over the stainless pods to block the side water, and are easily removed for cleaning everything. See the pic.Some notes on cleaning: I’ve found it best to set the used pod on the sink to let it cool a bit, but then tapping the grounds out and cleaning the pod before the grounds dry – if you let them dry then they’re harder to remove. Something that came with our coffee grinder has been very valuable in cleaning these – a brush (see pic). It allows you to brush stubborn grains out of the corners in the bottom, and the chisel tip helps get grounds out if you’ve left the used pod in the coffee Keurig overnight. Hopefully you have something like this or can find one to buy – a stiff artist’s brush would work fine. But it's best to clean the pods while still wet and warm if you can.- - - - - -- - - - - -Plastic waste: doing the math, comparing the costs, and cutting down on plastic:There’s been a lot written online about the cost of buying K-cups and the plastic waste involved. It’s easy enough to do the math yourself, so I did and discovered that most journalists must not be good at math, and/or are far too willing to accept anything someone tells them – the numbers being repeated and spread online are way off.A popular notion that I have seen in several articles online is that k-cups cost up to 40x the cost of traditional coffee. My simple math below shows that the price of k-cups compared to an equivalent amount of decent coffee is roughly equal, but I imagine most coffee enthusiasts use more coffee than what’s found in a k-cup, so they’re spending more… possibly much more.(EDIT: we are spending more... almost 50% more... because this system requires more coffee to yield a potent cup, even with the green side shields pictured. But the return is MUCH BETTER COFFEE EVERY MORNING. And of course, no plastic waste.)In regard to plastic waste, there are similar “facts” found repeatedly online. One states that the number of k-cups thrown out annually in American homes could circle the globe 12 times, while another "expert" says “I think it’s closer to 14 times.”Well how about 190 times? That’s the number I get from easily obtained statistics, a little math, and two big (but reasonable) assumptions/estimates: that 25% of American households use a Keurig machine (not my estimate... mine would be higher) and that the average number of cups brewed per day in these households is 4 (my estimate). Let's put that aside and look at cost first:The following is a rough comparison of the cost for pods vs. grinding your own (I’m using 360 days in a year for simplicity):My wife and I use an average of 4 k-cups per day, or 1440 per year. The amount of coffee in a k-cup is .4 oz by weight (I weighed it on our incredibly accurate kitchen scale). That means you can get approximately 40 home-ground k-cups (I’ll call the home-made version "pods" hereafter) out of a pound of coffee.At the time of this original post, a box of 120 Kirkland k-cups from Costco cost about $38 (Kirkland coffee is reportedly supplied by Starbucks). 1440 cups a year requires 12 of these boxes, or $456.12 ounces of Pete’s Cafe Domingo whole beans from Walmart cost about $9 (way back in 2021) and provides coffee for 30 home-prepared pods (“pods” to differentiate from k-cups). 1440 cups a year requires 48 of these bags, or $432.Costco K-cups for a year: $456Walmart-derived theoretical pods for a year: $432EDIT: But that’s based on theoretically putting .4oz of coffee in these stainless “pods.” In reality, I use .6oz of fresh-ground coffee for each pod (measured by my incredibly accurate scale with tare ability). So my annual coffee cost is 50% higher than the theoretical amount:K-cups for a year: $456Actual pods for a year: $648It clearly doesn’t make economic sense, so why bother grinding your own?Taste is a primary reason – fresh-ground coffee is FAR more satisfying than pre-ground coffee. Who knows how long that Costco or Walmart coffee has been sitting on the shelf (answer: way, way longer than the beans you will grind as needed).Variety is another reason – grinding your own allows you to choose locally roasted beans or a huge global offering of beans that aren’t available as k-cups.However, I’d argue that the biggest reason is the environment. My wife and I throw (threw) away at least 1440 k-cups a year, but it’s estimated that 32.5 million American households use Keurig machines (25% of 130 million households). If even remotely accurate, and assuming 4 cups average per day, that’s 47,450,000,000, or over 47 billion k-cups thrown away each year by American homes alone… corporate usage only adds to this number (the US is likely the greatest user of Keurig machines – despite the foreign-sounding name, Keurig was a US startup). It has been estimated that the number of k-cups used yearly in American homes alone could circle the globe 14 times, but the numbers above would indicate more like 190 times. An even more staggering mental image is that this string of discarded k-cups would reach from New York to Australia *every day* and would circle the globe every two days!(do the math... a k-cup is 2" in diameter… I’ll leave you to find the diameter of the Earth :)Keurig claims their cups are recyclable, but that is misleading. Recycling a k-cup requires the foil lid to be removed and the plastic to be reclaimed with industrial equipment. There is very little financial incentive in gathering, cleaning and processing the myriad tiny containers for recycling, so it simply doesn’t happen at any meaningful scale.A better solution is to make them compostable (as some have), and I agree, but the compostable products so far still require processing to remove plastic and foil, and again that’s just not gonna happen. So the honest reality is that the word “compostable” is mostly a marketing gimmick at this point.It is much better to just avoid the waste altogether by grinding your own coffee and reusing metal pods like the ones offered here. Better taste, choice of beans, zero plastic waste, very little time to prepare and clean afterward. Seems like a no-brainer to me.[EDIT 10/6/23]We have had two cups out of ten that have had the tiny hinge pin fall out – they are still completely functional, so it's not a big deal. You can replace the pin if you find it (it was easy for me to find both of our missing pins), and crimp the hinge with needle-nose pliers – that seems to work well, and the lid still functions perfectly. If the pin is lost, the cup is still functional – you just have to fit the top on by lining up the hinge – not a big deal.

I bought these for my Hamilton Beach 49979 FlexBrew Single-Serve Coffee Maker, after some disastrous experiences with the grounds basket that came with the unit (I have a separate review for that). Altogether, these are a good solution.First, these actually do fit the 49979 model without forcing the lid shut on top of them, unlike other reusable cups I've tried. You do have to press a little bit to get it fully closed, but not to the extent I feel like I'm straining and damaging the unit. They hold about two tablespoons of grounds, which is exactly what I want to use for a single cup of coffee. So far so good.On the down side, because these are designed like a sieve, where k-cups literally have a *single* hole punched in the bottom (who designs these things?), they make weak coffee without finding some way to block the holes in the sides. I read another review that suggested putting the stainless steel cup in an old, cleaned out k-cup to solve this problem. I had to cut off the top lip and the bottom of the k-cup to get it to fit around the stainless steel one - otherwise, it lifted the stainless steel cup too high for the lid to close - but this has been a good solution. The coffee is strong enough for my taste, and no more mess from the basket that came with my unit.Note that this does get some grounds powder, and occasionally a bigger ground or two, in the bottom of your coffee. As far as I can tell, the only real way to avoid that is by using filters of some kind (I believe this brand sells disposable ones that fit their reusable cups). This isn't a big deal for me, since I get basically the same thing in the bottom of a cup of cocoa, but if it's a deal breaker for anyone reading this review, you might want to find a different product, or use filters.Altogether, very happy I'm able to reliably have freshly ground coffee with my single serve maker. If the manufacturer reads this review, though, please stop designing your cups to make weak coffee! They do not need to have holes (or mesh) all down the sides, just in the bottom of the cup! Thanks!

I thought my Keurig just needed to be replaced , since it was like 3+ year. It constantly leaked , and splashed coffee around . These as you can see made with special fitting which made a big difference. No more mess. Well made. And I put them I’d dishwasher , far away from direct water.

Great price and quick ship/receive. As Arnie says, “I’ll be back!”

This works very well; the steel is a great option for those who don't want to have a lot of plastic in their lives (although the Keurig machine is almost all plastic - but whatever. Fits the Keurig well, easy to clean.Five stars for everything except in the description it says "It can withstand years of use."; in my case that was 18 months, and the hinge broke and the lid came off. For a long time I didn't use these, as I was brewing pots of coffee - and since I have two of these no single one was used every day; this morning it just fell apart. Because it's all steel it can be repaired, but that will take needle-nose pliers and a magnifying glass.

I no longer have to buy paper liners for my plastic filters! These stainless steel liners don't leak the grounds into my coffee !!! They clean up fairly easy !!! Love them !

These work great in our iCoffee machine. Sturdy and easy to use. Lid is a bit tighter to close but not to make them unusable.

No plastic touches the water or grounds. The coffee tastes better than with the re-usable one that came with our machine. Sturdy. Works with our K-Express. The only downside is when you want to make 2 cups of coffee back to back. The used k-cup is too hot to handle, so having 2 is perfect. You can take the used one out (the plastic around the edge is handleable) and set it to cool then use the other one.

Ordered these pods for my Instant Dual Pod Plus machine, but they are too long and I cannot close the lid.Otherwise, they seem to be well made of high quality materials.

We tried other stainless steel pods but they got stuck in the Keurig. These ones are perfect and with the hinge they are super easy to fill with coffee.

I wanted to avoid plastic so I looked at these. The lid is still plastic which was a bit disappointing but I like the stainless steel
