Query: Worthless For Electric Warmth

I've tried this product 3 times, for three different beds, and every single one of them stopped working within a few weeks: they did not heat at all, the connection to the blanket fell out every time you moved and you'd have to reconnect it and replug it and hopelessly hope; and the blanket itself did not suffice. I cannot believe that so many stores only stock this brand of warming blanket! Unbelievable! Go elsewhere to save yourself a major disappointment (and more chilly nights!).
