We have used Nora for three months. It works well. You put an inflatable thing in your pillow case, under your pillow. You put the little egg thing next to the bed, or stick it on the headboard. The egg detects if you are snoring, and causes the inflatable thing to inflate. The inflatable thing raises the Snorer's head-without weaking him- but the change in the neck/tongue situation causes the snoring to stop. It is not totally perfect. But it totally works the vast majority of the time. Literally, this thing is a blessing and a modern miracle. For us, well worth the price. And no, I have nothing to do with the company. I am just a woman who sleeps with a man who snored.
