Not bad, but be careful ...

I ordered this patch because I often suffer from headaches that come out of the neck.
The delivery was quick and easy, everything good. Can attach Alone they are not, because curl up quite quickly. Once installed you relatively quickly a pleasant feeling, one has the feeling that these patches give a special stop.
For here much criticized durability, I can not say much, because the plaster broke with me on the skin a alltergische reaction, which is why I recommend every user to test it first a few hours on an inconspicuous part of the body. When pulling off, I realized also that the adhesive can not be bad, because the withdrawal was already very painful, but this can also come from the allergic reaction.
In principle, therefore quite times worth trying, in my case it did not work out.
