I have installed five of this product over the last 20 years. I find it very convenient for greater cleaning of dishes, especially the dog's water bowl! I use it to preheat my coffee cup, make tea and soups. The only issue that I have is that in the last 14 years, i have replaced this equipment four times due to leaking around the cord. They have been professionally installed by a plumber, so the problem is not with the installation. Perhaps product improvement is needed for the tank.
