Streetwise Nap Zapper

The Nap Zapper is a simple device that could just save your life- or help you keep your job! The small, flexible device rests comfortably over the top of your ear and will sound an alarm to wake you if you start to doze and your head nods forward. Perfect for sleepy drivers or someone working the late shift. It works great for security guards, machine operators, and even students struggling to stay awake while studying. It is small and lightweight (approximately the size of an external hearing aid). The flexible rubber rests comfortably over the top of your ear. Switch from the audible alarm function, to vibrate for crowded settings, to off when not in use. Covered under a year warranty. Dimensions: 2 e x 2 x e inches. Includes three LR41 Batteries
