The knee bandage smells extremely strong for plastic. Only because of the smell, I have my doubts whether the skin contact with this product is healthy. On my knees, they can not fix it properly so that it constantly slips me. It has a rectangular fit and is adapted to the joint by cutting her in any way, or cut down on one knee. Maybe you have to have slender legs, so it is seated properly. An attempt was worth it. If you had bad experiences with such inexpensive bandages, should go in a medical supply store. In addition, orthopedic surgeons also prescribe bandages. Unfortunately, you can usually wait six months until you get an appointment. The bandage is more of a burden than a relief for me.
With regard to the smell, the manufacturer writes:
You will find the plastic very strong, but it is not plastic but EVA gasket, neoprene and spring steel plate, it is soft and sufficiently rigorous. They worry about the smell, can you please put it on the window and taking sunbath for a few days?
Under comments I put two links available that deal with this plastic, if it should interest anyone.
