Review title: As advertized ~
Product review: The BatteryBug is a nifty, though perhaps overpriced, electronic gizmo that is allowing me to keep an older battery in a car that MUST start, every time (read: wife's car). One minor puzzlement: the percentage reading the device gives is never identified as a percentage of WHAT, either in the directions or on the company website. But the acceptable threshold values are clearly noted, so that doesn't affect the usefulness of the device.
