Lasted 3 months...so disappointed

I bought this as a replacement for the last heating pad I had. It was this same make a model. This version does not get hot even on the hottest setting. I have to check to make sure it is on. The rough side gets a little hotter the the soft side.Disappointing the last one was so perfect. Update I purchased this November 13th and I have the Flashing F on it.
