My flashlight will not turn off

This is what i did to make it work (by pure guesswork).
1. take the battery holder thing out.
2. see black arrow on side of battery holder, that needs to point toward the led end when you insert it.
3. Look at the end of the battery holder, at the end that will go in first when you insert it. On each end there is that silver metal circle that has some silver metal extensions that go straight across the bottom.
4. look into the flashlight toward the led end. See the green circular circuit board thing. You'll see that equally around that circular base, there are 4 little squares of metal right to the edge of the green base, equidistant around the green circle. Carefully insert the battery holder with the silver metal strip on the holder lined up so each end of that strip will touch one of the 4 little square metal things on the edge of the green circuit board. The goal is that when the battery holder is all the way in, the two metal extensions coming out from the little circular metal piece on the end of the battery holder will each touch one of the little square metal pieces on the green base.
5. Screw on the lid and click the end to turn on the light. I tried this two times and both times it worked. If it doesn't turn on you might want to try to reinsert it again and get it more carefully lined up.
Good luck.
