Massdrop won't let me leave a review for some reason, so I cant 3 star rate this.
Ive had the brass version for at least a year. I used to carry it everywhere for about 3 months and haven't used it since. The light flickers constantly and im always fidgeting with the body of the light to make sure its tight but that doesn't always seem to be the issue. The finish was beautiful, when the light isn't flickering it is very bright, its small so it takes up very little pocket real estate and its so light you barely know its there. Overall I would never buy this again since its just the same old struggle I've had with any cheap flashlight... the flickering! It looks pretty but not reliable.
ZeroAirJust seen your comment now. Gave it a try. The driver barely moved any further but the problem seems to have gone away so I'm hoping that was the issue.
Thanks!
