I've had two of these things now. Which is fun because you can mix parts for different color combos. I love this little light. It's always been bright enough for me. I've had some issues with the tail cap partially unscrewing itself in my pocket. But after two years in my pocket I can understand it. Battery life has been sufficient for my needs. It's extremely durable. I sent one through the wash once. Worked fine afterwards. All in all I would recommend this to anyone looking for a quality every day carry light.
