Works, but ink bleeds
First the positives. I have a large head and it fits me just fine. Not sure if others who commented got shipped a wrong size or a manufacturing goof, but it works for me. I did get a small cloth to put behind the velcro as it did irritate me as well. (If the seller reads these, I would flip the velcro and cloth pieces so the velcro points OUT!) It has solved the problem for me of my mouth popping open and creating a cyclone noise at night, as my wife calls it. The main negative I have is that the black color is bleeding off. After a few nights, I noticed a bruise above my temple and thought I had it on too tight. After no change after an adjustment, I put a foam make-up pad under the area by the size adjustment clip. The next morning, it had a black outline of the strap. Since then, I have noticed discoloration on my CPAP strap and my pillow case. May try washing it to see if that resolves the issue.
