## Customer Reviews

### ⭐⭐⭐⭐⭐ Really good product well pleased with the purchase.

Quick installation!!! This was even better than I expected. Great choice Exceeded my expectations. Really easy to use. The water temperature is perfect! Easy installation.

### ⭐⭐⭐⭐⭐ Works great, space saving, endless hot water. Good value.
*by Y***N on May 16, 2025*

In our setup: maximum flow of 5 GPM (It's Rated @ 3.3 GPM) the maximum outlet water temp is around 90° F with 40° inlet water temp. With reduced flow (3 GPM) the water heater produces constant 130° F hot water (too hot for us) so we set the temp to 125° F and we're very pleased. Good quality unit. Easy install.

### ⭐ Not hot with decent flow!
*by D***Y on April 30, 2025*

This is for sinks only, do not turn the water on too much, or you won't get hot water.
