This Schulterwärmer looks more like a partially cut tube and bears no resemblance to the picture !!! The first somewhat scratchy feeling on the skin, which is common to all thermal fabrics gave it after 2 days, unfortunately, however, the portability, since this Schulterwärmer neck einrollte so strong and apply much more because of the thickness of the fabric, as other Schulterwärmer. Unpleasant is that this "Schulterwärmer" ever turned over the shoulder joints backwards, so that the joints are not heated properly.
The shipping expenses of Euro 10,50 I found outrageous, because they increase the actual product price of EUR 17.95 by 58.5 percent to EUR 28.45 and are therefore proud far more expensive than the other competitors.
Addendum: This was the first product, with which I am not at all happy with Amazon.
