The products listed above are of the Quality I desire in a product when considering a high end kitchen renovation. In our case this meant complementing our new Cambria Quartz counter tops with products that would last for many years. I gave my old ISE 77 to my daughter who was also doing a kitchen upgrade. It worked fine and still does. I wanted the ISE brand because I was familiar with their quality and ease of installation. My intentions were to use my existing hot water tank and just buy the F-H 3300 dispenser but later learned my old unit had an issue and wasn't so sure I wanted to do so. I called the ISE phone number and through some checking learned that my tank was obsolete. The person on the phone was very helpful and saved me a considerable amount on a new one. LIKE
