We purchased one of these dual coffee makers in our other seasonal home. Love it, so purchased a second for this home, and, sorry to say, have had troubles with it.  Support was very helpful by sending us new parts to try, and finally, a whole new machine. The latest new machine gave us one cup of coffee, then blowup of grounds in every cup thereafter.  So disappointed, no sense in spending more time on the phone with their support, we're going to accept defeat, and find a different brand.
