Review on ☕ Cafe Flow Stainless Steel Reusable K Cup, 2-Pack by Perfect Pod - Refillable Capsule Cup Metal Coffee Filter for Keurig 1.0, 2.0, K-Duo, K-Slim Plus & More | Check Compatibility Chart by Richard Dean

The large hole in the top allows you to pour out a large amount of ground coffee, so do not turn it on its side, otherwise you will have to wipe off the coffee grounds and refill. Some silly design, I DO NOT RECOMMEND buying a cheaper one, this one can last forever, but believe me you will be mad about it long before and throw it away or give it good will, especially at the $20 price point REALLY? Return or throw away if you don't like it, you're tired of cleaning up afterwards
