Fantastic for chronically cold feet
I've been using this type of electric booties for a number of years, as I have chronically cold feet - even if the rest of me is overly warm. There is always a replacement in my closet as I never want to be without. My last set made it a over a year though some last just a few months before burning out. I buy whichever brand is available at the time.
