I actually bought one of said 2-packs last year (or was it two years ago?). They ARE exceptionally bright lights for the price, but the build quality, despite being thick metal, leaves something to be desired, particularly the internal electronics. I kept one in my gun bag, and just recently pulled it out to use it, only to discover that at some point, the internals detonated into about 10 different pieces. As far as I can tell, it's unrepairable. However, the other one is still going strong. I'm not sure if the one was just a lemon, or what. Still, even if only one out of two is good, $30 still isn't a bad price for how bright they are, and they ARE still decent quality. Although I guess at that point, I'd just run down to Target and pick up an Inova instead, but.... That's just me.
One of these days, I'm going to get off my lazy butt (on my day off), take some night pictures and do a half-decent review of my many flashlights... Eventually. Or so I keep telling people. lol
