alertme™ Lifesaver Driver Alert
About the size of a bluetooth earpiece and lightweight, less than an ounce, the alertme™ is the latest and safest lifesaver electronic device that helps prevent accidents caused by falling asleep behind the wheel. The alertme™ device works by detecting when the user’s head nods while driving or working which indicates that you may be feeling drowsy. Its ergonomic design makes it very comfortable to wear and improves your vigilance on the road.
