Query: Shame on inSinkErator

I purchased this product 3 years ago. When it works it is a fabulous addition to my kitchen and makes my life easier. However, problems abound and InSinkErator doesn't stand behind the product and repair parts and costs are excessive. After one year of regular use the initial tank started leaking. Insinkerator sent a new cheap tank and 6 months later it no longer heated the water to the usual super hot temp. Also after 2 years of regular use the hot water spurts out around the top of the nozzle endpiece to spray water everywhere. Insinkerator refuses to stand by their $350 product and they have a monopoly on the market for instant hot water dispensers. Shame on them. I currently am putting up with this problematic system because I can't find a better product.
