I wanted to see if this works well with partially discharged (low) batteries, and it actually works. Even without using fresh batteries, the light seemed nice and bright and could be seen from a distance. He tells me that with fewer new batteries, this will work until the batteries die. This is important if your car gets stuck when using it in your car (which is probably the best use of this article). It has a nice strong magnet on the bottom for easy attachment to the top of your car or any metal the magnets will work with. Batteries are so easy to change. The lower part unscrews to reveal the battery compartment. It looks pretty well made; no cheap flimsy plastic that will soon break. Even though it's mostly plastic, it's of good quality. Good price for your safety. I have nothing to criticize about this article. It's simple, well made and works! Features an on/off switch and 2 different strobe patterns.
