Save your money, time, and hope - it did not work
If you have a mild snoring issue, this might work okay for you.  However, for someone (like my husband) who has mild sleep apnea and snores loudly, this product did not work even after a solid week of attempts.  The air wasn't strong enough to make any difference, plus the unit would fall out (no matter how far he applied it in his nostrils) within minutes.  The battery life is short (didn't last all night, even having charged an entire day) and ultimately, I feel it was a waste of our money, time, and energy.  When a spouse is DESPERATE for sleep and something like this pops up or comes along, we grab on to the hope of a snore-less night and ultimately pay dearly for it.  This is NOT the device it claims to be.  Save your money - go to your doctor, and request a sleep study.
