I've had one of these for a few years
"It has been on my key ring the whole time and still works! I like the fact that I can access the strobe with three quick presses. I use it when walking dark streets and parking lots. The only downside is the really lame audio alarm, which isn't very loud and turns on accidentally in pocket. I glued the switch so it's not a problem now. Wonder if I should buy a spare. I've tried several other key lights and they either lack an easy strobe feature or they are too big and complex. This SGN5 is just right in size and complexity."
