Small and lightweight, 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. When active, the alarm emits a 90 decibels sound which is the equivalent to a police whistle. Its ergonomic design makes it very comfortable to wear and improves your vigilance on the road.
