Well, I'm no pro on the heat tape topic, but years ago i.lived in a mobile home, and it's the norm to plug your heat tape in when the nights get cold enough to freeze the water main, I always left mine plugged in ALL winter, not sayin they can't fail, as anything is prone to failure, but I think you just got unlucky.
This one is working good, I think I'm going to use a 6' on the 3.5 gallon waterer I have in the Cochin run
I probably did get unlucky. It was new out of the package as well. But they are also designed to come on when the temp of the pipes in a house gets cold enough, mine would have been on 24/7 since the ambient temp was always below freezing.
Mine lasted until about mid Feb, the coldest part of the year.
Not easily serviceable, it would be faster to make a new one from scratch.
