This is the second time I have installed this system. The original lasted about 7 years with a temporary repair 2 years ago to stop a leak in the tank. This new unit looks to be identical to the old one so I would guess it will have a similar life expectancy. I struggled with the price of this replacement but was not able to find another hot/cool system that was competitively priced. I think this unit is very good quality but has a harsh environment that shortens its life.
Easy to install if you have the correct hole pattern on your sink and a little room under it. Nice appearance.
Bottom line is that it will give you both cool water and instant hot water where you need it most for a price.
Pros: Easy to Install, Looks Great
