A workshop cluttered with a rat's nest of extension cords isn't just unsightly – it's unsafe. One solution is the classic cord reel, which spools cords on a wheel for easy access – but also has the tendency to snap back like an overly aggressive tape measure, whipping into anything in its way. A better idea: Press a button on the RoboReel Power Cord System, and its motorized wheel automatically respools a 50-foot cord at a safe speed. Bonus: It has sensors that automatically kill the motor if you step on the cord. [$330; roboreel.com]
