Here's a hi-tech solution for a mundane household task: positioning and arranging objects level onto a wall. A laser line guide beats out the old fashioned vial-style level, allowing alignment of art frames, audio speakers, and other objects from great distances, with hands-off positioning (adhesive mounting kit included), and a magnetic barrel and belt clip designed for toting around after you're done perfectly arranging art onto the wall like a boss.
