Para guitarradeespana09/06/2014The heat and vibration around your neck works to relieve neck pain. I can feel the vibration running gown my spine. Was so relaxed, I fell asleep with this. Does not automatically turn itself off, but is safe to use. One setting only, but works great! We love using this when we wake up early and the temperature is cold. Wonderful product, beats using aspirin! Will buy more as Christmas gifts.
Para guitarradeespana03/05/2014Bought this for my husband. He gets severe migraines that can disable him for several days. I was worried he was taking too much medication to relieve migraines. He could not sleep. Surprised my husband with this, and he LOVES it! When he can feel a migraine coming on, he sits on recliner and puts this belt around his neck. Belt gets warm, vibration replaces my hands rubbing his neck. He can use for two hours at a time, falls asleep wearing it, relieving migraine. Safe and effective! Bought one for
