Save money AND protect your electrical equipment with the SMART STRIP surge protector. Plug anything that must always be on into one of the three "always on" outlets (like a fridge or fax machine) and then plug a "control" appliance into the white area like your computer with peripherals like a printer in the gray areas. When you turn-off the "control" appliance, it will turn off everything else EXCEPT the always on units. It also ensures that your appliances aren't drawing energy when they are plugged in but are off (called "phantom loads.") 10-outlets, 6-foot power cord, $200,000 protected equipment warranty, 2100 joules.
