Noalto Reusable K Cups and Coffee Pods,Universal stainless steel k Cups for Keurig 2.0 and 1.0 Coffee Makers machine(2pack)

I love these. My wife uses them as is, and is fine with the results. I like my coffee much stronger. More like espresso. We use one grinder with a blend of espresso blend and a really good decaf. I don't want to have a second grinder. So we use the same blend. These leave a few grounds and silt in the coffee that I don't like, so I bought some paper filters. But the paper filters don't work well if there's no paper top. Maybe water seeps down the side, avoiding the grounds? With the paper top, it's very weak. So I punch a hole in the top for the lid spout. See the pics. I also over fill the basket and tamp it down just by tapping the basket on the counter. Using a press is too much. Lastly, adjusting the grind so as to hit the right size for the variables to ensure no bitter or sour taste. The result is a pretty good coffee. Full flavoured, not bitter or sour. They are solid construction and super easy to clean. It's been a couple of months now, and no rust.

These work wonderfully with my Keurig K-Supreme Single Serve K-Cup Pod Coffee Maker. Works quickly and precisely, with no coffee grounds in our coffee. SOOO much better than the one that comes with the coffee maker. Cleans easily. There are replacement bands that wrap around the base at the top, in order to get a snug fit when dropped into the K-cup adapter. VERY happy with this product!

These work well, easy to fill and easy to clean.

When I first saw these I thought they were kind of expensive, but after receiving them I can see they're very well made and should last a long time. And having used them for a few days now I can say I'm quite happy with the coffee I brew with these. After reading some reviews saying refillable cups make weaker coffee I decided to get an extra dark roast, and the results are a very strong cup of coffee, so I don't think I actually needed to go with a bolder roast. I may post an update after I've tried some different ones. These have a very fine mesh, I'm pretty sure the holes are a lot smaller than most similar products, which I think helps the brewing process. I get a small amount of grounds in the bottom of my cup, but not nearly as much as with a french press. I've been using two tablespoons of medium ground coffee, which fills it to the top, and then I tap the whole thing on the counter to settle it and it gives it just enough clearance for the dispersal nozzle without packing it too tight.

Work good for me. Brews coffee the way I like it. Only issue is the rubber washer often falls off when washing and can be tricky to put back on sometimes.
