Perfect Little Light
Reviewed by WilliamA from Kansas City, Missouri on Thursday, May 9, 2013
An absolutely perfect little light. Small & unobtrusive yet very bright. I have bought 7 of these so far. We are putting one in each bug out backpack, our medical backpack, on the zipper pulls of our sleeping bags, & on zipper pulls of our Gore-Tex parkas. I know I'll end up buying more, as I want t...

  • Never worked
    Verified Buyer Reviewed by Aaron from Arkansas on Friday, August 11, 2017
    Didn't work out of the package. Popped it open to make sure there wasn't a plastic strip on the battery that needed to be pulled off. This item is as cheaply made as was possible. It's pitiful that Princeton Tec would put their name on it. More of an item you would usually receive for free at a conference.
  • Great key chain light

    Just what I needed to find keyholes in the dark. And at a terrific price!
  • Great compact light
    Verified Buyer Reviewed by Nori from Bannack, Montana on Tuesday, December 1, 2015
    I have three that I've kept on keychains for several years -- just ordered three more for my kids. Use them for about 30 seconds once every few months -- but when I need to use it, I REALLY need it to work right, and these definitely do! Compact, weightless, functional light. Perfect for its niche!

    Verified Buyer Reviewed by Bcville from Virginia on Monday, November 16, 2015
    I have bought 5 of these, and as the days get darker I might get some more.
    They are small even for keychain lights. I have one clipped on my messenger bag, so when I cant see steps or a path I can just reach down and click it on. Plenty of light for that.
    It isnt a substitute for a flashlight, but it's a great substitute for darkness.

  • “Are the batteries replaceable, or do we have to throw away after the 10 hour battery life?”
    Asked by Laura from Unknown on 8/13/2012 12:00:00 AM
    • Batteries can be replaced if you are careful in prying open the case, and not letting pieces fall out of place. You'll need good finger dexterity.

  • “Hi,|Does this light have a 'blink' or 'flash' setting?”
    Asked by Vic from Glendale, CA on 9/1/2011 12:00:00 AM
    • This key chain does not have a flash setting. You squeeze the body to turn it on or off.
      Answered on 9/6/2011 12:00:00 AM by Anonymous from None
    • This item does not have a "blink" setting, however it will hold a steady beam without constant pressure.

    • No.

    • No ...stays on switch
      Answered on 11/27/2011 12:00:00 AM by Bill the tinker from Sherman
    • No. The switch will let you keep the light on hands-free, or you can set it so it will only come on when you squeeze it. But it doesn't blink.
      Answered on 12/26/2011 12:00:00 AM by displaced californian from Allyn, WA
    • No, but it takes very little pressure to make it blink yourself. The switch has three settings: Constant light; pressure setting; and off.
