## Customer Reviews

### ⭐ My electrician couldn’t get them to work
*by K***Y on June 13, 2025*

My electrician had a really tough time getting this to work correctly. Eventually forcing me to swap out with a different brand and return these. The water would come out scalding hot even if I turned the temps to minimums on the unit. After running for a while the LED displays would only display “E4” error code. I had 6 all with the same issues. Waste of time and money

### ⭐⭐⭐⭐⭐ Great buy
