    If you want a flashlight that you can carry in your pants pocket without feeling loaded down, this one’s for you. I’ve owned three of them but that’s because I tend to “misplace” or lose them. I carried one on me all the time. I love it.

    The brightness levels are well chosen, nice beam, and the control is grea. But unfortunately I will not be getting any more of these because although this is the perfect personal light it has absolutely no means of attaching it to a keychain, belt loop or backpack, the teeny tiny lanyard holes are useless, the lanyard broke the first day. If you try to tether it by the clip, the clip and light eventually separate. I eventually zip tied a parachute cord to the light.which is not ideal at all but that’t the only thing that worked. Great little light otherwise. It’s a shame.

    The flashlight is a very nice size, looks nice, and the switch feels great! My only gripe is the pocket clip does not slide over the pocket. The clip does not have enough clearance to fit over pocket. I just use a small split ring in the lanyard hole, with a small S-Biner to clip it to my pocket. I definitely like that it has three modes vs the competition AA flashlight, that has only two modes.
