I’ve got a few of these and they drive me nuts with all of the different settings but they are really bright. They’re a little big to keep in my pocket so they just get used around the house or for hunting.

I’ve carried a LED mini mag at work for several years. Mainly because it’s slim design is comfortable in my pocket and I was tired of buttons breaking on other brands. Mine has started dimming and flashing randomly but goes away if I tap it on something hard. Whenever this one dies I’ll probably get a little streamlight.
