It has only two "adhesive corners" that once glued, are no longer handled better.
Unfortunately, the part from slipping yet and is not placed in different movements.
In the manual is, sensitive people and older people to stick it onto the T-shirt. I can hardly imagine that it holds the first place there and secondly warms. I'm now not really a lot of heat felt.
Would not buy again. Then since you Besse operated by a Kirschkernkissen, reusable and cheaper in the long run and especially hot!
