It looks high-tech, but upon closer inspection it's hard to imagine who wouldn't find use for Gecko Grip Level from Black and Decker. No ordinary bubble-in-a-tube tool, the Gecko is equipped with specially designed Gripper pads to hug the wall, preventing the level from slipping while you mark your target. And in an extra stroke of genius, designers built in sliding "Accumark" tools, which allow you to pinpoint the precise distance between the nail and the top of the frame. (No more estimating with thumb and forefinger). So go ahead; decorate those empty white walls!
