Two things I did not like about; Both Screws for thermostat covers were kinda stripped, I had to pry cover away while unscrewing to remove cover to check temperature settings. Secondary, on lower thermostat I had to remove white plastic safety cover in order to read temperature settings numbers.j

Perfect for condo

Would Recommend

Excellent product, easy to install, fast heating. Only 38 gallons but I have never run out of hot water. Small size made easier handling.

Just Installed, Time will Tell, Too Early To Rate

Would Recommend

Too early to rate. 6 year warranty I believe. My plumber installed. Other than looks, not much I can say yet. I hope it will last a very long time.
