Very Good Light
This is a very good light and that isn't considering the low price. It's just good in general. The price makes it even better. The light itself appears to be built well. Light is a bit of a cooler tone but almost neutral. Hotspot in the center of the light is BRIGHT. Can illuminate things well at quite a distance. Beam itself isn't perfect but will not matter or even be noticed by virtually anybody buying it. The pressure switch works. It mounts fine. Everything works. Now I love paying for quality but I just cannot fathom how someone will spend $400+ on an arguably worse flashlight and a better pressure switch from a competitor. This is as good or better in ways for almost 1/3 the price. People say "oh the military uses that brand!" Great. Most police and fire departments use Streamlight and like them. Some say "oh the other brand is made in America!" Yeah they're an american company. They manufacture some things in the U.S. but look on the box or the light itself. You will not see "Made in U.S.A." on it, because there are parts of the light not made in America. Streamlight is also an American company. So you can spend 1/3 the money on this better flashlight trusted by our first responders or you can buy a 3x as expensive light that actually illuminates things worse and isn't even technically made in America. Either way you're supporting an American company. I'd highly recommend buying Streamlight.

Would buy again
Amazing light. It mounts very easily to my rail and the attachment to turn it on/off/strobe also amounts very easily to the top of my rail so I can control it with my thumb. Strong light, great battery life. Not sure how size compared to others, but I am OK with the size of this as it isn’t too big in my opinion. buttons are also extremely smooth and low profile.

88066 Pro Tac Rail Mount Light
I trust Streamlight as I have a TLR-7 and the build quality, fit and finish really impressed me for the price, and the brightness was very good (it’s bright enough that looking directly into it will nearly blind you temporarily). It also was great in how it attached, ease of use etc. I liked everything about it, so I went with Streamlight for this purchase as well. I have no complaints so far, it seems like a solid light and basically exactly what I expected (I haven’t used the switch, as I feel I can thumb the button just as easily with it on the left side, and won’t accidentally hit it). The brightness is just as strong as I expected as well. In regard to a review talking about getting a fake one, I did not (mid 2022). The build quality is just as I’d expect, it’s robust and the finish is very nice. It’s very easy to attach to a pic rail (if you have an MLOK guard you just need a little pic rail, they’re cheap), and it has a hand-tightening nut attaching it. The nut has a slot cut into it as well so you can use a tool (a knife, whatever fits) if you ever needed to loosen it if it seizes up a bit. The only thing that surprised me a bit was the size. It’s a little bigger than I expected and hoped for, but that’s why you should research before buying anything lol. It’s fine honestly, just a little larger than I realized. I would’ve preferred a slightly smaller/lighter light, but the fact that it’s big enough to be used by hand is probably a benefit anyway. I suppose it’s a normal size for a light of this nature, I have never owned one so it’s new for me. It looks a little big on the there in terms of aesthetics, that’s all. If anything goes wrong with it I’ll update. But as of now I recommend it and I definitely recommend Streamlight. I like their products.

Great WL for the money.
Great value for the cost, I've run Sure fire lights in Iraq and TLR units when I taught civilian side. And this has held up just as well. Love the dual high/low mode. As anyone who's ever done close in room clearing will tell you, sometimes you CAN have to much light and it sucks catching yourself half blinded with bounce back. So being able to drop down with just a quick tap is great. Then when you get outside tap again for the extra throw to check woodlines or open fields. Do recommend a steel zip tie to lock it to weapon forearm just incase. It's easy to hit a doorframe going to fast and it keeps everything on the rifle in an emergency. Great buy, stop reading and order it.

Very sturdy and bright
I originally had an O-Light that I ended up giving to my father. I wasn't super pleased with the build but when I got the Streamlight (for maybe $50 more then I paid for the O-Light?) there was no going back! Such a great, sturdy build and is SUPER bright! Also has some great weight to it! Not too much, not too little!

GREAT LIGHT!
For the price of this light it’s great. The light is programmable by tapping the pressure pad and you have 3 programmable options. The mounting hardware is durable. The pressure pad is plastic but works great for most applications. I don’t recommend buying used like I have because not all of the hardware to mount the light was there. But overall a good option for budget minded folks or getting into WML

Extremely Bright
Great light. Incredibly bright. Mounts easily. I used a Schaffer Machine pressure switch mount for the pad. Excellent setup.

Better than expected. Uses two different types of batteries! Versatile.

No complaints here I've used it on my .223 and my shotgun. It just plain works, and holds up to even using slugs. Solid choice.

Really like the light. The mounting system for the pressure pad on a picitany rail isn’t the greatest, the plastic parts it comes with hold it on but it’s not sturdy. I might replace them or do a different mounting system. Overall the light is very bright and mounts to the gun very nicely. Very happy with the purchase for the reasonable price point

I've got a bunch of other lights in the same "lumen" category, however this is the brightest 2xCR123a light that I own. The ability to switch between tailcap and pressure pad is also great. It's a shame it only support 1913 rail. I drilled out the holes on the end and put some M- LOK T-Tnuts through to direct mount on an M-LOK rail (pressure pad only - light still 1913). Still on my first set of batteries so can't talk about battery life and haven't had it long enough to weigh in on durability. For the price seems like a very high value light.
