Great coffee maker! I have had a little over 2 weeks now and amazed how much improvement has been made over the last FlexBrew I had. The best part I enjoy is the 40 ounce k-cup reservoir. It brews hot and fast, and I don't have to keep pouring water in for each cup. I prefer the 8 ounce brew size for a stronger, better tasting cup of coffee, otherwise the coffee is too watered down. There is not much difference in the carafe side except there is no sight glass. They do have steps inside the water reservoir though marked with cup water levels. No complaints on this coffee maker! I think you will love it as much as I do!
