We've been using this for a couple months now and we love it. It's so versatile and very easy to use. We use the single serving side more often than the carafe side, but both sides work perfectly. We just don't often have a need for a whole pot, but when we do need to brew a whole pot, it's really nice to be able to use the same machine instead of having a separate brewer. I have used prepackaged K Cups and I have used regular ground coffee on the single serving side - either way makes a quick, tasty cup of coffee. I love that it holds so much water so I don't have to pour water into it every time I want a cup. We use this brewer daily and have had nothing but good experiences with it, no complaints! We love it!
