I had been using the FlexBrew Duo for about a year and absolutely loved that and upgraded to the Trio, which I now also absolutely love. I never want to do without the FlexBrew in my life! I set the easy touch programming every week night to have my carafe coffee ready when I wake up, and use the single cup throughout the week and weekends. It's fast and easy, with no clean up. I haven't had any clogging issues and overall I'm thrilled with this machine.
