My company uses these, I liked it so much at work I bought one for the house. Then I saw the one with a magnet, and THAT is the best tool for working under cars, you can stick it at a certain angle and it's better than having a friend hold the light. But the magnetic one isn't intrinsically safe and obviously it's a magnet so it should be kept away from electronics/monitors, which is where this light shines <<--- I really did that unintentionally.
