### ⭐⭐⭐⭐⭐ Great
*by S***E on 23 September 2023*

Great little heater. Not as hot as I thought it was going to be. Very good size. Nice and compact. Easy to install. Looks good too.

### ⭐⭐⭐⭐ Doesn't get very hot
*by V***4 on 7 August 2025*

Doesn't get hot but warm enough for our use.

### ⭐ broke in 10 minutes
*by M***O on 11 January 2024*

it was perfectly sealed, but it broke within 10 minutes of use, and was smelling like burned plastic. Definitely not recommended. is not heating much, unless you have a very low water pressure, but in any case it will burn out after couple minutes making it very unsafe, since it is water and electricity very close to each other.
