This is my fifth: third 12-cup and second  6-cup.  Although they do give out after a year or so, we use them both A LOT because the Presto is absolutely the only one that makes the coffee really hot and keeps it that way for many hours without it becoming muddy.  When it gets old and makes the coffee thinner, we simply replace the pot:  it's inexpensive and although we have several that cost up to six times as much, this is still the best.
