Even when they’re off, today’s electronics continue to draw electricity we pay for but don’t use. This revolutionary power strip prevents that waste. Plug your main device (computer, TV, etc.) into the primary outlet and its peripherals (printer/scanner or VCR/cable box, etc.) into the others. High-tech sensors know when you shut down the main device, and they cut off everything else. Saves up to 72% of the energy your systems use and offers state-of-the art surge protection too.
