J&J Electronics ER, Chesterfield

These days, electronic gadgets have become extensions of the human body. With such heavy use, accidents are bound to happen—and that's when the technicians at J&J Electronics ER swoop in to save the day. They don't roar onto the scene in an ambulance when a screen cracks, or wheel busted laptops into their shop on stretchers. They do, however, replace the LCD glass on Apple devices and rescue video game consoles from overheating issues. They also recover data on computers and eliminate viruses so owners don't have to spray Amoxicillin into USB ports.
