'Alert Master' keeps you up on the road  On-ear device wakes you
up if you nod off while  (Credit: Maplin Electronics)  This is a
perfect stocking stuffer, especially in preparation for late-
night holiday festivities. The "Drive Alert Master" from Maplin
Electronics is an over-the-ear device that's designed to keep
you awake no matter how much cheap champagne was served at your
company party.  It works like this: If your head suddenly drops
forward while you're behind the wheel, the Alert Master sounds a
loud beep just to make sure you're not nodding off. The
contraption seems a little bulky for the ear, but it's not meant
to be a fashion statement, and Shiny Shiny says it's apparently
not as uncomfortable as it looks. And for $10, it's a lot
cheaper than a new air bag.  CNET Top 5 Reasons not to buy the
