Very bright, sturdy build. I work on a dark room and this comes in very handy. The moonlight mode is bright enough to see at night and lasts forever. Love this thing. Gets warm at the highest lumen setting, but understandable. Strobe settings can dazzle intruder or attacker for couple of seconds.I have owned several tactical flashlights over the last few years. This one addresses some of the issues that I have had in the past with others. First off, the carrying clip is mounted very near the end of the light. The result is a design that doesn't overhang a pocket too much the way many other lights with the clip mounted more toward the middle of the light do. Next, the rubber flap that seals the charging port actually closes tightly. The failure of that simple part in other designs has really bothered me in the past. The switch has a nice solid feel to it and it is positioned in such a way as to make it unlikely to activate it unintentionally. And finally, it is really bright. I'm very satisfied.

This is by far my favorite flashlight and I carry at least 8-10 on me every day at work as a Building/Home Inspector.
I love the compact size and the ability to clip it right on my belt.
It's definitely the brightest light that I carry!

Overall,I’m happy with it. I’ve been wanting a 21700 light for a little more power and battery life than my Klarus E1(also a great light) and this G15 fit my needs perfectly.

Love this light. I replaced the clip with a deep pocket clip and can't brag enough about the light. Love how I can charge my cellphone with it.
