Idea is great: as a trauma nurse, I'm definitely more aware and thus paranoid of everything that can go wrong on the road. I loved the idea, and didn't mind paying a higher premium for a quality item. However, these do not plug in securely into the charging port in the car, they are very loose, and in a high impact crash, they would go flying. I store one in my arm rest area which completely defeats the purpose of this items design.
