Received the unit quickly (within the week I ordered it). First thing I noticed about the unit was the high quality materials used. Very nice internal digital display and a nice paint job without a bunch of safety warning stickers all over it. I would have like to see 3/4" water inlet and outlets as the rest of my system is all 3/4 but after using the unit I am very pleased with its flow. I also have not seen any error messages and like the fact that the unit shows actual output water temp as it warms up and stabilizes. This is my first tankless and installation took less than a day, changing from an electric 40 gal tank style. It does take a little bit longer to see hot water but the benefits far exceed the hassle of waiting. As this is my first tankless I didnít realize that it also provides a never ending consistent water temp. No more adjusting the faucet in mid shower to keep the water the same temp. The only draw back I see is that since I live in a cold climate, I need a backflow preventer in the vent system and I was unable to find a 3" appliance adapter with built in backflow preventer. Seems the only way to get one is to buy a 3" horizontal condensation drain with a built in backflow preventer which runs about $70+. Very pleased with this unit. Excellent choice if you can't shell out the big bucks for a Rinnai or Bosch.
