Product review (5 stars): Quality product just as advertised.
I uused this to create a water line freeze prevention heater.  It was 7W at 120V out of the box so I added a series resistor to bring it down in power. (Know what you are doing if you do this!! including getting a resistor that can dissipate the heat properly.)  My side by Side Frigidaire dispense line no longer freezes!  My Frigidaire did not have anything but 120V in the dispenser area so the common GE unit sold on Amazon (which runs on 12V, watch out for the smoke!!!)  would not work.
