Fantastic product, Indicator light is great!
Fantastic product, works as described. Helps keep my water manifolds at a site less prone to freezing when the weather gets colder. Love that they have a power indicator when in use and the thermostat seems to be spot on when I've been using it with our plumbing.

As advertised
This heat strip is very flexible and easy to wrap around a pipe. The indicator light in the plug ensures you have power to the strip. It doesn’t seem to get very warm to the touch so I’m waiting to see how well it performs when the outside temperature drops down below freezing. So far it, on the nights when it has dropped down cold outside, the pipe hasn’t frozen but, it hasn’t really been cold enough long enough to know for sure. If you use these strips, be sure to wrap some type of insulation around the pipe as well to hold in the heat from the strip. Otherwise it will not be nearly as effective in extremely cold windy conditions.

Good quality product.
I live in Frazier Park and my plumber said I need to replace my heat strip on my water line. It was easy to install and is a good quality product, I recommend buying it and it is reasonably priced. I have used other Frost King products and I have never been disappointed...

Good to Go
Installed on wellhead that has box w insulation over it and exterior freeze-proof faucet, so far so good. I like that it's not too cutesy w no elaborate controls ("press twice and hold for menu, press again for...") it's just on when you plug it in, plug and go

Performs well, not an adjustable length so measure accurately of what length Frost King you need
Very good heat kit. I used to use the Frostex heat kit, used them for many years, but there expensive and their controller cannot get wet. This Frost King is waterproof which is a big plus. This Frost King does Not have an adjustable wire length, you could cut the Frostex to fit but not these Frost Kings, so get an accurate measurement of what length you need. I had installed a 12-foot Frost King but it turned out to be too long, I had to remove it and install this 9 footer.
