FIVE Shiatsu Neck and Back Massager with Heat ($35)
"OK, I'll be the first to admit this massager looks like some sort of bizarre double arm sling/straight jacket, but for the price of $35, I figured it was worth a try, and I'm so glad I ordered. Those weird arm loops actually allow you to control the amount of pressure you apply to your body and the heat function on this baby works wonders if you get severe period cramps. Easily one of the best Amazon purchases I've ever made!" — Kelsey Kennick, editorial operations manager
