Review on ☕ GoodCups 4 Reusable K Cups: Compatible with Keurig K-Slim, K-Duo, K-Classic, K-Elite, K-Select, K-Cafe, K-Compact and More - Refillable Coffee Filters for 2.0 and 1.0 Brewers by Jon Thompson

Ordered these reusable K cups with minimal expectations. The reviews were mostly positive. Those who have complained about problems are either inexperienced or don't take their coffee seriously. I love these mugs! They are so easy to use that even my grown son can use them successfully. He doesn't have the patience and in most cases it's too difficult for him to pop a pre-packaged pod into the Keurig. But I digress. With these K mugs, you don't have to worry about three pieces of ground coffee sticking on the rim and opening. Don't worry about your machine rejecting the cup and telling you it's not compatible. They work perfectly every time. They are easy to clean and I recommend cleaning them after every few uses. You get more oils and finely ground coffee particles in your cup. I like it. Speaking of water filters. Well, they are filters. I inserted one. It works out. This is a quality combination at a great price. What else could you ask?
