Review on ✨ Beautyrest Heated Mattress Pad - 100% Cotton, Dual Temperature Control Electric Bed Warmer with 18" Deep Pocket, 20 Level Setting, Auto Shut Off Safety - Queen Size, Standard White by Clint Fick

I had no choice but to give it at least one star. If it was an option I would put a big fat zero. Although it worked fine for a while, it suddenly became impossible to stay on for more than a minute. I just decided to quit work and tuned out every time. Brrr. With a return window of about a month, I guess I have no choice but to contact the manufacturer. How painful. I should have bought a heated mattress topper from a store with a much better return policy like Costco, Kohl's, or Bed Bath and Beyond. But I actually expected it to work well for many years, like electric blankets from the same manufacturer.
