Input:
This is probably the 3 one of these that I have purchased.  The first on lasted many years, but eventually developed a leak somewhere in the heater.  The second one lasted about a year, but it pretty much was my fault in trying to clean coffee grounds out of the water chamber.  I think I got water in some of the electronics.  I could have bought cheaper, but this has been a steady performer.
