It works! Your mouth stays closed and your jaw is aligned comfortably.
I have been using a CPAP for years, mainly to stop severe snoring. I did not want to attempt a surgical fix and my doctor suggested, after a sleep study, to use the CPAP as a fix. That works, for sure, but is cumbersome and expensive. I have tried many fixes for snoring over the years, and they all do something, but not much. I tried this Dual Band on a whim and I must say it worked better than anything else I have tried. It is comfortable and doesn't interfere with my sleep. The two bands together work better than a simple chin strap ... you have to experiment a small bit to find the placements that works for you. But once you get it - it works! Your mouth stays closed and your jaw is aligned comfortably, it is as simple as that.
