I have been using my Keurig K15 for a couple days now and l seriously love it! The directions make it simple to use, and it is very fast and convenient. I was never a fan of coffee before, but now I drink it every morning. It does not make tea as strong as I like from the k-cup so I would recommend brewing hot water and steeping a tea bag yourself. If you like strong coffee, I would recommend brewing loose ground coffee in the k-cup reusable coffee filter, which is super easy. One thing that is a little frustrating is since it is small, you can only use a mug or short cup, because taller ones will not fit. However, overall it is an amazing product!
