Works as described
I bought these for my husband.  We've been married for 17 years and I have never become used to his snoring.<br />I think he has sleep apnea but he's too stubborn to get it checked out.  There's 4 sizes, he uses the middle one.<br />I can say that there is a huge difference in his snoring.  His nose whistles now and that's annoying but I'll take it over log sawing.  It took about 3 weeks before they started falling out during the night, so maybe they lose shape for stretch out. Overall he says they're a temporary discomfort compared to us being able to sleep in the same bed again.
