This heat tape has been great to prevent pipes from freezing in the unheated crawl space underneath my house. I live in a cold climate and heat tape is a must-have item if you have water pipes under your floor, as I do. However, please be aware that the heat tape really needs to have a layer of insulation on top of it in order to work most effectively. Long lengths of heat tape can be a bit of a pain to install in a crawl space that is pretty shallow, but that's the fault of my crawl space, not the heat tape! The indicator light on the plug is a handy feature if you have the heat tape plugged in where it's visible, but I'm not sure about the utility of such a light with the heat tape plugged in under my house, since my crawl space isn't readily accessible. It seems like the plug light would be more useful if you're using the heat tape in an unheated basement or some other application where walking around and checking on it is easier. This heat tape appears to be thick and durable, but only time will tell if it will be susceptible to rodent damage or other problems.
