Thinking about buying one? DON'T. I got mine from the mystery box awhile back and it never worked. Day 1 I had issues with it not turning on, or the button turning on the flashlight 2 minutes after pressing it. Smacking it seems to be just as reliable for turning it on as pressing the button lol. Based off the comments this is a regular issue with this crap. Don't waste another minute thinking about buying this junk.
