Review on Pre-Assembled 6Ft Self-Regulating Pipe Heating Cable - 120V By HEATIT For Efficient Winter Protection by Adam Hutchinson

Unfortunately, I didn't try to test this when I got it by placing it in a freezer to see if it would warm up. I am going to try and return it, but I am well past my Best Buy return period, so IDK. A few weeks ago, it got down into the 20s, and I decided to use this instead of filling my RV fresh water tank and unhooking the hose. Since it wasn't cold enough to turn on when I wrapped the hose with the tape, I walked away thinking I would wake up to good water pressure. Wrong. The hose was frozen and the tape was cold. I unwrapped the hose and put the tape in the freezer for a few days to test it at zero degrees. The tape never got warm, not even a little bit. Very disappointed. A complete waste of money. A brand-name product that is this expensive should "just work", or at least thats what I thought when I bought it, which is why I didn't think twice about not testing it as soon as I got it.
