content: Shipping was fast and unit was packaged well. The unit is slightly larger than I expected (2.7 gals) which made for some customizing in the under sink area, but installed nicely after that. Be sure to place a baking pan of some kind under installed unit to catch potential high heat discharge or other unpleasant occurance. Dialectric unions between unit and water source are also good materials to figure into installation to limit long term internal corrosion. It's nice to have hot water right away, without running it for two minutes, then having a long line of heated water cool down again and be wasted.
