If the chin strap allows that much jaw movement, how does it prevent the mouth from opening and allowing air escape while you sleep? I put a resmed chin strap on today to see how it feels and it didnt really seem to provide any real resistance. I will try it tonight but can't imagine how it will prevent me from opening my mouth while I sleep
The ResMed chinstrap is worthless. I could not keep it from sliding off, and even when it stays in place, it doesn't do much. I have been using spandex headbands as chinstraps. The stretchy material works well for a few days, until it gets too stretched out. Then I wash them with my whites to shrink them so I can use them again.
I purchased a Puresom Ruby chinstrap, which is very well-made, and has the same springy action as the spandex. Unfortunately it was too small for me, so I had to place an order for a larger size.
