It works! My husband started using it on Monday and I have heard 2 snores (not episodes, 2 sounds on 2 separate nights). I do NOT hear Nora inflating at all and I am an extremely light sleeper. Prior to the Nora he snored off & on ALL night. I wore earplugs, made pillow tarriers, used a white noise machine & still woke up. The only thing that worked before was a mouth thing that hurt his jaw. Nora is amazing! We both wake up well rested. And trust me, I was skeptical.
