Hello, I've had my Keurig since early or mid-November 2010 and we have used it almost everyday since for tea (k-cup or teabag) and coffee and we have had absolutely no problems out of it. I love it! I have never dranked this much coffee. My reason for purchasing was similar to a couple of posts above about the coffee being made early and then by the time I'm ready for my cup it was lukewarm or my husband made it too strong. This is great, because we each can have it the way we like, no messy filters/coffee grinds to deal with. Really quite simple to operate and maintain so far.
