Ok, so this is could be beneficial only because of a placebo, affect, but I saw it on a Tiktok, and figured why not? When you have debilitating insomnia, you'll try pretty much anything. I've used it 3 nights in a row, and all three nights, I've been asleep in under 45 mins, and have been able to get back to sleep fairly quickly, by turning it back on when I wake. My only gripe is that the wrist grip is a lil tight (and I'm a woman), and without having it on your wrist, it easily gets lost in the sheets, and NOTHIN' will wake you up like rooting around in the sheets for 20 mins trying to find your sleep aide device. If you're in a situation where you can gamble with 30 bucks give or take, it's def worth a shot IMHO.
