This is by far the best one out there. You will never need another light. Magnetic, super bright, huge pattern, stays lit for 3 to 4 hours. Everybody that buys one of these never uses a trouble light again. The cover ( has magnets built into it) is made of soft rubber and will not scratch. If the battery is about 15 minutes from expiring, a yellow led will light and warn you. The hook in the pic folds away neatly when not needed, and when used is on a click click type swivel. When you head under a car, this is all you will take. About 125 dollars...and worth every penny.
This is one of the best Christmas gifts I ever received,
Its called a Quantum Leap
