I love the mask; however, they should make it XL. I had to add an extension to be able to use it, and my ears hurt because they are super tight. I understand that some people are tiny, but not in the US. The other problem is that it is costly, if I want to use it twice a week. It is not going to work. I wonder if the mask can be reused, like washing it and using it again with conductive gel, or would it be wrong?
