Reusable K Cups | Refillable K cups Supreme & Supreme Plus Coffee Makers

I was skeptical about purchasing these cups. I decided to do so because I drink coffee throughout the day. The k cup pods were a storage headache and didn’t like all the plastic waste it contributed to environment. I checked to make sure these were the right ones for my kureig. The coffee taste SO fresh. I also love that I am saving money and going green. They work great!

Fits perfect. I just pop the adapter and cup in and out with my husbands regular one. It's also nice to have a clean cup on hand . The lid comes off easily from the cup. Also be sure to line up the arrow on the top of the cup with the arrow on the adapter before closing the lid. It should be pointing to the front of the machine. Haven't had any leakage issues. Would recommend for K Supreme.

These are Stainless Steel which was a top requirement to get away from plastic K-Cups. We use a Columbian Coffee that tastes better than most K-Cup pre-packaged brands. There's an extra step involved in cleaning these, but we don't mind since we also save our coffee grounds for our garden. A small brush helps with getting leftover oil and grounds off while rinsing.

My husband uses every day and loves them….nice that they are stainless steel and not plastic.

The stainless adaptor seemed well made and was perfect for my Keurig Supreme. However, the silicone seal that allows the cap to snugly fit the cup kept coming off and eventually would not stay on at all. I requested a replacement instead of a refund and received two stainless adapters that appeared to have been a new design with a plastic insert to distribute water from the multiple Supreme fill ports. The insert failed immediately and would not remain seated during brewing. I returned both for refund. Its a shame. I really liked the stainless filter bottom as it was effective and easy to clean.

One works great in our K Duo 2. The other has a defect in the gasket for the lid. That one works ok but has some leaking, the lid doesn’t seal tight. Debating on replacing.

I did not realize how much we were getting ripped off by the disposable cartridge makers. By using these refillable cartridges, we get a cup coffee that tastes as full as that from a coffee bar at a small fraction of the price we were paying for the disposable cartridges. We started off using the paper cartridge inserts and the tried it without the papers. Both ways are good. Going without the cartridge gives a more robust flavor (micro-fines allowed to pass into the cup). However, the cartridge rinse-out takes another 10 seconds if you don't use the paper insert. So, basically, it's a tradeoff. Either way, you will love these re-usable cartridges!

The lid does not stay attached to the cup. There is a rubber seal on the lid but you have to grasp both, the lid and the cup when moving, otherwise they come apart with or without coffee inside. It fits flush with the Keurig so taking it out is messy, I got wet coffee grounds on the machine attempting to fish out the cup the first time. Also, the cup has a higher bottom than portrayed and my usual 6oz scoop of coffee is too much. The instructions say to fill up to half or 2/3 of the way up which results in less coffee than I'm used to.
