Query: Fine...for a while

We purchased this coffeemaker for its sharp retro styling and because Cuisinart tends to be a reliable brand. It worked fine for several months, and then began having difficulty brewing. The heater simply burns off water into steam so 12 cups of water might slowly brew only 8 cups of very, very strong coffee. We tried cleaning it, brewing only 10 cups at a time, varying the grind size...nothing worked. A phone call to Cuisinart very impressively resulted in a no-hassle replacement with a new unit. However, the new unit soon presented the same problems as the previous one. We know how to read and carefully followed the instructions provided in the manual, but it makes no difference. We are now looking around for a less expensive Mr. Coffee or other brand. Not as sharp looking, but in the end, you can't pour a snazzy appearance into a mug and drink it.
