It only worked for my EX-husband when he slept in a proper position. People who roll around at all, it doesn't work. So if you're a still sleeper - great, us these. If you're NOT, you're not gonna get much use out of them. Also, if you live without a good A/C and you're going to sweat at all while you're sleeping, they'll peel right off UNLESS you use the "sports" ones.
