Hi Mark, I purchased a Ratio 6 and though very pleased with it, thought the carafe was a bit clunky. Our family takes our coffee very seriously so we decided to splurge on a Ratio 8. We think the 8 makes better coffee than the 6, which is still very good, and we feel the carafe is much nicer for pouring. But, the water reservoir on the Ratio 6 does not empty completely after brewing coffee and that is a problem. I don't like old water to collect in the machine. I've actually gone back to using the 6, which is a shame. Have any other customers had this problem? Could I exchange it. Or, what would you suggest? Thanks.
