Everyone has experienced drowsiness while driving. Some of us have actually fallen asleep only to be awakened by the blaring horn of an oncoming car. Avoid this potential tragedy by wearing the Nap Alarm on your ear. If your head should nod, an alarm will go off, waking you and any sleeping passengers in the vehicle. Uses three AG13 alkaline button cell batteries (included).

(1) Many of them arrive in non-working condition. We ordered 2, and one worked and one didn't. Read the other reviews if you don't believe me. (2) It is not adjustable, and either doesn't fit one's head (for the men, generally), or is so large it slides off (on women, generally). It is difficult or impossible to wear with glasses. (3) Worst of all, there is no way to replace the battery, so if you do get one that works, it is effectively a disposable product, something that was NOT disclosed in the product description (in fact, most of the descriptions state that it takes an A13 "button" battery). (4) And good luck getting rid of it: it contains a glass mercury switch with a big blob of mercury in it.
Do not buy this product.
You have to position it correctly to get it to go off at the right time. Regardless of how you position it, hard braking will trip the gravity switch and it will alarm at you. It's... well, alarming at first, because it seems counterintuitive that it should go off when your head is held up. Once you get used to that you'll appreciate that it's doing its job.
There are radar detectors which are have a "keep the driver awake" feature. They are much more expensive than this little thing, but safer too: what if you doze off without nodding your head? I have a homemade version of the radar detector feature (having majored in electrical engineering), so actually I'll be driving with both systems to keep me awake .... :)
Remember: the best system is a bed and 3 hours of sleep. Or just pull over and doze for 20-30 minutes at a convenience store or rest stop, that does me a lot of good....
