Review: Simple, but effective - I don't know why never explain how their devices work, but here it is. The operation is pretty simple. You set the temperature by regulating the flow of water. The device has various protections, but it always operates at maximum power, so to increase the temperature you need to reduce the flow. Keep it away from water or steam as the electronics inside are not waterproofed whatsoever.
Review: Good while it works .... lasted 6 months before it died - Requires a dedicated outlet to prevent breaker from tripping, running for more than a few minutes can sometimes trip the dedicated breaker as well. Purchased in February, finally got in installed by mid June. It just stopped working in November. To get the water more than just warm water flow has to be low, barely enough to wash your hands. Used in work shop and was able to get the pressure where it worked for me. While it was working I gave it a 3 or 4, but since it worked barely 6 months it gets the one star it deserves

### ⭐⭐⭐⭐⭐ Great little tankless Water Heater
*by R***B on January 27, 2025*

This heater takes up a very small footprint. It does a good job of quickly heating the water within a few seconds. However, you need to know a few things before ordering it. Per the item description, it works best with a limited flow faucet. The water gets quite hot with a 0.5CFM faucet, just barely warm enough for a shower with a 1.0CFM faucet, and does a good job of taking off the chill with a 1.5CFM faucet. Its rated at 3000watts (25Amps) of electrical power. My home is fairly new construction and has a 20Amp circuit breaker for the bathroom. The heater drew 2600Watts (22Amps) for 30 seconds and then the circuit breaker popped. You will need a 25-30Amp breaker to power this heater.
