This was purchased as a spare heater, in case the one that's installed now malfunctions.
Fast shipping, next day. It was a replacement for the exact same thing so I'm happy with it. Works well.
The heater went in easily and heated my tub quite quickly.
It appears well built and only time will tell as to it's durability.
