It works like a champ. Taking 40-45 seconds to get the real hot water (set 120 degree F). It has a function to reduce water flow when water is not hot enough, and then the valve opens in full mode when the water reaches its pre-set temperature (save water). Workmanship is outstanding in high quality thoroughly. Surprisingly, Print Circuit Board (PCB) is sealed completely with epoxy to prevent moisture. All electronic components are selected such as cables, connectors, switches. Hardwares also in high quality and selected. I am totally happy with this buy. I downloaded its manual from Rheem site, it is not updated and lack of information, compare to paper manual attached to the unit. Thanks Rheem and Tankless Water Heater Depot! :)

No complaints. Works as intended. Really enjoy the endless supply of hot water. While it may not be the case for everyone, there is a noticeably longer wait time to get hot water at the tap compared to the tank heater we replaced. That is more of a tank vs tank less issue though, not this particular unit. Will have to look into a circulation pump.
