It is amazing to have instant hot water at ones touch and not have to wait for the hot water from the water heater to get to you faucet. It also nice to be able to not have to heat water on the stove for hot cocoa or tea or other drinks or food that require hot water.....one of the best things you can get, especially for the person that thinks they have everything!!! When I needed to talk to someone in customer service, he was extremely helpful and seemed to go the extra length to see I was taken care of....keep up the grreat job!
