Oh my God yes, I bought one of these about 10 years ago it’s still going strong and whenever I get a little cold I just turn it on and it’s so nice.

Another thing that I found is amazing is putting them in your shoes are slippers for about 5-10 minutes before you use them, because it means when you put your shoes on they’re not super cold so it feels like you’re putting them in hot water instead of cold slippers
