I have had my sleep appliance for almost a year. It works very well for me and my wife just loves it. My CPAP leaked a lot and would wake my wife. She would then wake me to say it was leaking and keeping her awake. With this sleep appliance, leaks are a thing of the past. My wife now sleeps all night long and doesn’t complain and wake me so I sleep all night also. It’s great for traveling.
