Ever had times when you couldn't remember the last several miles of a trip, missed your exit, or wandered toward the shoulder or median? It happens to everyone...you're exhausted, but keep driving anyway. The IntelliDoze alert can literally be a lifesaver for drowsy drivers. It fits discreetly behind the ear and alerts you with a beep, vibration, or beep + vibration when your head starts to nod forward. The IntelliDoze is rechargeable with a USB cable, and includes chargers for 12v and 110v. Hint: the vibrate mode can be useful at work, too, if you hit the 3 pm sag every day!
