I just stumbled across a device on the net called a "Doze alert." It's marketed to sleepy drivers. It looks like a hearing aid, in that it fits over and behind the ear. The ad states that it will make a buzzing noise if the person's head tilts as if nodding off. It costs $40 USD, and batteries are an additional $15 USD.
The ad is at http://www.dozealert.../Doze_brch.htm.
Before I spend money on this thing, has anyone else ever tried it? Is it useful?
Is The "Doze Alert" Device Useful?
