Extremely disappointed in this product. After nearly a year of daily use, it began beeping constantly, with the LED display flashing numbers. It wouldn't respond to any input, and the display froze on "Ec2" after I plugged it back in, still unresponsive. 

I drink (drank, I suppose) only half a pot every day, and I took good care of the product. 

I don't think I'll be buying from this company again.
