Bright idea
If you are looking for a reliable gun light, this is for you. Streamlight is a well known brand, and this product is representative of the quality they are known for. Easy to install on M-lock rail, with included hardware to do so. The battery has to be removed to charge, only a minor hassle. This is at a good price for value.

Invest in this, no regrets
Can’t say anymore than this, streamlight makes top level gear. This light is smaller than a lot of other offering out there, battery is rechargeable, mount kit keeps it tight on a black rifle, and the pressure pad is tactile and smooth. I definitely prefer the price to other options, and the warranty is great if needed. Extremely bright. You won’t regret it.

Streamlight makes great lights for the money
I've used streamlight for probably 10+ years. Their lights are amazing for the money. They're easily half the price of their competitors, sometimes more than half, and they work amazingly well. The light is really bright, definitely not the brightest on the market but absolutely up there with the top competitors. I've carried a ProTac handheld light for probably 10 years. I used it working security and just as my every day carry. That thing was beat to hell and still works great. This is the weapon mounted version, so if I had to bet this is probably just as durable. A really awesome point I didn't know when I bought it and I don't see in the listing is that this light uses the surefire m600 mounting system. Any light mount that working with the m600 (and m300 I believe) will work with this light. It's a great feature that adds to the versatility and value of the light. I recently bought a mount and will update with photos when it comes. One negative I do have to say is the pressure switch isn't great. You have to press more towards the back of the switch to get a full output beam. The on/off button can have light pressure applied to achieve the same result as the regular pressure pad but I doubt most people would have the fine motor skills to do that consistently under stress. After some practice it's not hard to consistently hit the correct spot on the pad but I just wish it was a little more forgiving. Ultimately, if you're looking to buy a solid weapon light to get rid of that stupid UTG one you bought when you didn't know any better, this is definitely a good entry into the high end market that allows you to get the most for your money.

This is a nice product that does what I wanted
This is my first rifle-mount light; the illumination is very good even at the low-power setting. I'm still working out the best way to mount the remote switch, and they give you parts to get it done if you already have picatinny rails. The 10-tap programming works, although, it seemed odd at first. Turns out you don't need to switch settings all that often, if at all, once you got it the way you want. I had no idea if 1000 lumens was too much or not enough, but it seems plenty bright to light up an area even 50 yards away. I think the low setting is 60 lumens and is plenty good for most things inside (i.e., finding keys, stuff under the fridge, etc.), and it runs a lot longer than the bright setting. Construction is sturdy and reasonably light for its size. It's nice having a rechargeable battery since the CR123s are not cheap. The bigger part of the rail clamp is integrally built into the body tube, so it won't be coming off (the thumb wheel, bolt, and half the rail clamp look like they can be taken off). The packaging is fine. Manuals are very small print with versions in English, Spanish, French, and German. Overall, I'm very happy with it. I gave 5-stars because it works for me even being inexperienced with this kind of product. Lastly, even if the shipping was delayed because of massive snow, it still got to me on time.

Awesome product, but the battery was DOA.
I ordered this after hearing good things and having very good experiences with Streamlight in the past. The light has a good, solid mounting option. The light it self is bright, programmable and useful to about 150-250 yards depending on the conditions. For indoor conditions the throw is wide and bright enough to illuminate most of the room but the hotspot on the high “setting” is right on the edge of being too bright. The only real complaints are the tail switch reduces the waterproofing rating and the battery was dead on arrival. Pressure pad mounting system is annoying to put on but does the job well. I tried to use Amazon’s “replacement of broken or missing parts” option and spoke with no one who could understand plain English and they kept trying to return the item for me; despite specifically stating I just wanted them to send a replacement battery ( Amazon has the replacement battery for sale). I ended up having to contacting Streamlight directly because Amazon’s customer service was useless. Needless to say Streamlight’s customer service was down to earth and wanted to help immediately, they shipped the replacement with no hassle, no questions asked. Awesome customer service on Streamlights part.

Great WML
Worth every penny. Bright, mounts easy, plenty of slack to pressure pad.

Highly effective
How did I do without this for so long. Ordered two by accident, one is AR-mounted and the other on the shotty. You'll need to plug the charger into the battery in case that wasn't clear on the page. Seriously bright. Setup was simple and once you sort out the hand/switch location it's intuitive. Highly recommended.
