    Car battery voltage stabilizer

    Has anyone ever used one of these? Does it do anything at all? They are cheap and looks easy to install, but it sounds like snake oil or one of those $69 perfoermance chips. http://www.ebay.com/itm/170700743637?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
