I bought this laser here some time ago, and I'm rather pleased with it. I don't recall what I paid for it, but I believe it was on sale or discounted or something. The normal price is steep in my opinion. With that said, I'm very pleased with the performance. It's very very bright, to the point that you can see the beam itself at night, which looks really cool. I've only taken it to the range once, but it performed very well. Some people apparently have issues with it cutting out while shooting, maybe I haven't shot enough with it, but I've had no problems so far. Battery life seems decent, and batteries are readily available and relatively inexpensive at walmart. Very easy to use, and the buttons are well placed and ambidextrous. It looks very cool on my Glock 19, matches the color of the frame very well, but it is a little bulky for a laser, and extends maybe a half inch past the bottom of the trigger guard. It's not much of a problem, but it does make finding a compatible holster a little difficult, as I haven't had a whole lot of luck, but I'm sure there's something out there. A little frustratingly, Viridian makes a nice tacloc holster for their universal lasers, but not for these, and these aren't compatible with them. Alternatively, there are plenty of reasonably priced custom holsters around that could be made to fit. Overall, very happy with the laser so far, and when it's not on the glock, it makes a great dog toy laser that doesn't break after the first 5 minutes of use.
