    Switch on by it self when in my pocket attached to keys. Now it stays the bathroom just in case power goes out. Need to add a bright red LED for night.

    Not what I was expecting from a keychain light. Very Bright! The three different brightness setting are nice because on high this little light will illuminate a dark room. The built-in usb rechargeable battery is a nice, no batteries to replace, and it has a battery level indicator so you know when it needs charged. The battery last long and holds a charge in between uses. I got it before Christmas and only charged it once. I do not carry or use it every day, and I do not have it on a key chain, but I can see how it could turn on in your pocket or bag very easy. (A complaint in other reviews) The on/off button sticks out farther then the top of light and it only needs pressed for a half second to turn on. I think if the button was recessed or had a lock switch, could fix the turning on accidentally problem. All and all very happy with light.

    Bright enough little edc light but poor switch design- anything in your pocket that bumps into the switch turns the light on and drains the battery. I always notice this at the end of the day when it’s dark…solid build but poor execution; waste of $15.00. Other 2 Fenix lights are great so not giving up on the brand!

    Just received 3 of these. They seem to work well when charged. The switch is easily turned on. They discharge quickly in my jeans front pocket. I recharged one and it held charge fine outside my jeans. Need to find a better place to carry it.

    Very useful light for your keys! So small you hardly notice it. USB charging is convenient and the battery indicator is a nice touch. Very wide beam and even spread, which is ideal for close up illumination in the dark. Run time and battery life is superb as well. I wish the color was a bit warmer but overall an excellent light. Good job Fenix!
