Received in excellent condition: installation was simple and I'm glad I ordered the 24" wires. Works great and NO LEAKS! Thank you, Master Spa Parts, for your telephone guidance!

Fit perfect. I also used the new gaskets and was done in no time. Works great, no leaks!
Verified Buyer
This part is a great and easy replacement for my original heater. All I had to do was remove my heater and install the new gaskets (which came with the heater) and tighten up the fittings and make the power connections. It took my 1/2 an hour to fix.
