This was a direct replacement in my spa and fixed an issue where the heater stopped working properly and would not heat above 95d. I was also getting a FL error on my panel which meant there was a Flow problem. Replaced with this new one and it's all good now.
Product was exactly what was described on the web site. It fits perfectly.
As always-great service & support.
Fit no problem and tub is heating once again
Been using spa depot for over 20 years always provided as described parts and great customer support with quality parts
