I've purchased 5 of these now, one for me and the others to use as gifts and everyone loves them. My one sister goes tail-gating for football games and she says it keeps her nice and warm while they are standing out in the parking lot. They're not bulky so it can be worn under a jacket or coat. I usually turn it on low and once it heats up I can usually turn it off as it keeps me nice and warm.

I really like that this company has an American front end. Makes it much easier to exchange or return. I have the insulated vest. I wear it almost every day to stay warm through a tough medical period. I had a little trouble with sizing and customer service at the beginning. But one of the owners jumped in, immediately addressed the customer service issue.

Everyone that looks at it likes it, they always ask me about it, and best of all: IT WORKS LIKE A CHARM!!!! I work outdoors and once I get going with setting up and prep work, off goes the hat and the heavy coat. Once I turn it on, I can immediately feel the warmth through my core therefore my arms and legs are able to keep warm on their own.

This is my 2nd vest. Only because my husband has mentioned he would like one so I got him one for Christmas this year. He bought me one for Christmas last year. I wear mine to work in a meat processing plant and use it all day every day. I do have 2 batteries, because I have the heated jacket too. Yes. I'm spoiled like that.

Ordered it after trying out a different brand. This heats up faster and hotter thus not needing to run it on high. Was worried one small sized battery wouldnt last long enough for a round of golf, but it retains heat very well making it unnecessary to run it on high. Having the battery pouch off to the side makes it easier to play golf. No longer have to be cold during winter this this vest.
