May not offer a cure for snoring but fantastic for opening up the nasal passages. I have been unable to breath through my nose and sleep for ever and these have been brilliant. They don't seem to do much looking in the mirror but you'll feel the difference immediately breathing. Perfect for those who suffer swollen nasal tissues. I wear them in bed and when training and I see other athletes with them constantly. One thing; I have tried the clear and tan and find the tan stick better. Found a couple of the clear ones loose in the bed in the morning and they either fell off or I scratched them off due to itching. I have never had that problem with the tan ones.
