My better half gave me a gold star for getting her this!
After eating out a local restaurant that used these for the outdoor seating, I ordered this for her as she feels cold quite often, while anything over 70 makes me uncomfortable.  This, coupled with an electric kettle, has solved the eternal fight over the thermostat, the only downside that every 4-5hours I have to reheat water. Small price to pay in my opinion.  After a month of continuous use, it still feels as good as the day we received it.  I have not received any complaints from my better half, with the exception that she would like another one.
