Product review (5 stars): Has worked flawlessly for almost 5 years
We're very happy with this product.  We installed this under our kitchen sink in the fall of 2007.  It has worked flawlessly ever since.  We have hot water in less than a minute, save lots of water, and can barely hear the pump running.  If anything, I sometimes wish it was a little louder because it is difficult to tell when the pump turns off.  I have to open the door under the sink to hear it switch off when the hot water arrives.  The price seems to be much higher than what we paid in 2007, but that is probably because it is made in Australia, and their dollar has become much, much stronger in the last 5 years.  It seems pretty pricey now, but I'm not sure what the competition is like.
