You`ve been sitting at your computer all day. With the deadline looming, you didnt even get up to break for lunch. Your eyes are starting to cross, your shoulders are tense and your neck can barely move. Finally you cant take it no more. You get up, bend your head to one side. Creak. Then to the other side. Crack. Finally you grab your favorite new purchase–this sinfully delightful massager. You slip it around your neck, relax back, press the button, and ahhhhh, relief. 2 speed button touch vibration action. Uses 2 AA batteries (not included) Great for use at home, office or on the road.
