Fill N Save Elite Series Stainless Steel Reusable K Cup for Keurig 2.0 and Backward Compatible With Original Keurig 1.0 Models. Works with Keurig Machines and Other Single Cup Brewers, 2 Pack

These are rugged and should last a long time. But you need to know a few things before you buy:First, because the holes the coffee passes through are much smaller than in Fill 'N Save's plastic models, you may have to adjust the grind you use to prevent excessive pressure build-up and resulting leakage during brew. It can push past the rim seal, even when using the seal hack appearing in another review (use of a tiny rubber donut from Lowe's under the Keurig's top piercing needle seal, to increase tightness).This brew cup gets very HOT to the touch so you need to be careful removing it unless it has had time to cool down. Yes, plastic also gets hot but metal has a higher specific heat and conducts that energy to your fingers more readily. So be VERY careful. Yes, they tell you to grasp it by the plastic "ears" under the rim. But those ears are NOT as shown in the photos. They've made a design change from the semi-circular bumps shown to a tiny flat ear, making it a lot harder to avoid the hot metal. And that's not all the design change did...The two ears in the photo were designed to fit into depressions on opposite sides of the Keurig pod holder, thereby assuring proper orientation so the bottom piercing needle on the Keurig was nested in the depressions on the Fill 'N Save brew pod's bottom. With the new flat ears the Fill 'N Save has to be carefully aligned (its lid hinge at 6 or 12 o'clock, meaning at North or South). Otherwise a ham-fisted person could damage the bottom of the Fill 'N Save (or possibly the bottom needle on the Keurig) by abruptly shutting the Keurig's hood. BTW, the plastic models WILL be easily damaged in that way, as their bottom mesh screen is no match for the Keurig's needle. See my review for them of 11 May 2016, which also discusses the coffee grind and fill to use.Last...and probably least...coffee grounds are much harder to get out of this stainless steel model. I use a spray nozzle at the sink and it still takes patience. Getting coffee out of their plastic models is much easier, perhaps due to the plastic flexing when rapped on the side of the sink or waste bin...(?) The plastic ones actually seem to work better for me, other than the fact their design flaw makes them very vulnerable to damage.

Fill N Save *ELITE SERIES* 2 pack Stainless Steel Reusable K Cup. Built to Outlast Your Keurig Machine! For Original Keurig 1.0 and New Keurig 2.0, K200, K300, K400, K500 Series of Machines I bought these because we thought our little helper had tossed our plastic reusable Kcup. Found it after making a cup of coffee for my fiance with one of these. *half smiles* Anywho, I was rushing to get his cup of joe since I was late getting him up for work, but wanted a cup of coffee to surprise him with, so didn't bother washing first (normally I wash, *then* use).First cup was really nice...more flavorful coffee, though I did notice a bit of clouding at the bottom of the cup. This might have something to do with the oil in your machine or grinder, so make sure you clean such implements regularly! Cleaning, though still easy, is a bit harder with the steel cup. With no paper filter, the grounds tend to stick to the bottom/side, so you'll need to rotate it while throwing the grounds out/removing them from the cup. Rinsing slightly different, too - start from the bottom, then do the sides, while still pointing the opening downward. Rinse the lid last, without letting grounds get back into the cup. We're using a finely ground coffee until it runs out, and I've noticed tiny grounds leftover, so will need a wash at least every other cup of coffee if you do the same, depending on how picky you are about that kind of thing.As others have mentioned, this is METAL, so let it cool for at least a few seconds before removing from your Keurig or you'll burn your fingers..Every cup of coffee we've had since the first has been much better than with the plastic K-cup - one of the reasons I haven't mentioned yet is because of the nice little "spray" effect as the water enters the cup. Look on the lid - in the center, there's a black V shape, dotted with holes to allow the water to hit more of the grounds as it goes through.The price is up there, so without a need presenting itself for another K-cup, I doubt I'll be purchasing again. Plus, these things feel and look like they're built to LAST, so I also don't foresee the need to purchase for myself again, barring a certain little 2 year old trying to be helpful & tossing them. I would, however, gift them! Definitely worth it, in my opinion, as you save money over the lifetime of the steel cups, not to mention fewer (none, maybe?) chemicals entering your hot drinks through the cup itself, so potentially fewer health issues.All in all, if you have or know someone with a Keurig, I highly recommend getting at least one of these - two if there's more than two people using a single machine. We're very satisfied with ours!*Will update if we decide to try the paper filters inside this cup.*

IMPORTANT: YOU MUST use the orange stickers on your K-Cups when using a Keurig 2.0 machine.I've never used Keurig and just bought the machine. I only bought it to make coffee making cleaner and simpler--so I bought these slightly expensive (must be a heck of a mark-up), little stainless steel K-Cups.Again, I've never used a Keurig coffee maker until I got this one.I put the-is over-priced stainless steel K-Cup in the machine, closed it and the machine told me it was not an official Keurig product and gave me an 800 number to call Keurig.I re-read the tiny instruction card and realized I should not have thrown away what I thought at the time was a useless set of orange stickers (In the Coffee world "Orange" is used for DEcrap, oops, "Decaf," and since I don't drink decaf I'd thrown them away. Do NOT throw away the orange "decaf" stickers. They have nothing to do with decaf.It turns out that those orange stickers are HOW these over-priced stainless steel K-Cups trick the computer in the Keurig 2.0 machine.And While I like the Keurig machine, I think the makers of these $ 1.73 made in China, over-priced stainless steel K-Cups need to revisit the lid and use orange plastic insert pieces in the stainless steel lid instead of requiring users to maintain stickers! I know that would increase the manufacturing price by $ 0.91 cents per lid but then the sellers could charge $ 30, $ 40 or perhaps even $ 50 for these over-priced stainless steel K-Cups.
