I've had instant hot water dispensers in my kitchen for mor than 20 years and find them to be very handy. This Insinkerator model works as well as any I've owned; howerver, I had to repurchase it after the first one failed after a little more than one year. I was in my kitchen one afternoon when I saw what appeared to be smoke coming from the cabinet under the sink where the unit was installed. I determined it was coming from the hot water dispenser and so I of course immediately unplugged the unit. The smoke (which I surmised was actually steam) quickly dissipated. I was thankful I was present when this issue arose. The fact that I repurchased the same unit obviously shows I still like the product but have made sure I saved the receipt in case a simimar issue occurs. I also now unplug the unit when I'm away on trips as I do with other electric devices with heating elements.
