The design is brilliant. It wraps around my neck perfectly and stays in place even when i lean back on the sofa. The best part is the "simulated hand" technology. It doesn't just vibrate mindlessly; the massaging nodes move in a way that's exactly like a professional masseuse's hands,kneading, pressing, and rolling along the tense muscles at the base of my skull and down my neck. I was shocked at how precise it is; it hits those hard-to-reach knots that i usually can't get to on my own.
