It worked great for my husband. We have used it for maybe a year? As soon as they came out we got one. About a week ago for about 3 days it seemed to quit making him not snore. We figured out we had put the thing under the pillow the wrong side up when we changed sheets. Didn't realize it made a difference but it sure does. Working great again. I wonder if some of you that returned it maybe had the thingy under the pillow upside down too. Love this thing.
