Good idea but very poor design would not recommend
The concept behind this product is great, however, the overall design is terrible. The area of the vest where the heating element lies does not cover the areas it is intended to be used on and the tie strap is incredibly short. I am not a very big person, not very tall and don't weigh very much, 130 lb and the extra large size wouldn't even tie in front of me so I had to leave it just hanging. If you lean back such as on a couch or in a chair it pulls down on the neck part and you feel like you're choking. The neck hole is way too small for even a small person. I returned it, it did not fit in a way that it provided any usefulness.
