Bests & Worsts Reviews from Amazon

I received my Delibru 4 Pack Reusable K-Cups and these reusable k-cups have been working just fine. Like some people have mentioned in the comments, the compaction of the ground coffee is the key to making great tasting coffee. If you overfill and over-compact the coffee grounds in the k-cup, the water will not filter through the coffee and will overflow from the top of the k-cup. I typically fill the k-cup 3/4 of the way with loose coffee grinds, tap it on the counter two or three times, and then run it through the machine. These k-cups are very easy to clean, just run it through hot water to clean the cups. I recommend this product to others!
