“I bought this vest for me and the same vest for my wife in the female version . I’m dissatisfied with both vest because when you put it on the hottest setting it will only stay on that for a short period of time and automatically drop the median level. Also the vest does not get warm enough unless you really push it against your body. I really thought the quality would be better. I would love to have been able to exchange it if there is better performing vest but this was a holiday sale and it showed as final sale.”
