According to my wife I snore less with this pillow.I don't really like it, it's hard to get used to, (took me two months of try it for half an hour then go back to my old pillow, etc) was very expensive, the pillowcase ripped right away (That pissed me off I now just throw it in a regular pillowcase that's ugly but OK). I'll use it 'til I can replace it.Now that I know that it's possible to reduce snoring with a pillow, I see that there are others out there when I google 'snore pillows.' I'll try some of the others to compare. But... my wife says I'm snoring less since I started using this one.
