OTW Rifle LED Flashlight-Tatical Weaver Pistol Gun Handgun 500LM LED Flashlight Weapon Light for 20mm Picatinny Rail

Came with 2 batteries, so that's something. It also makes lights sometimes. Now for the negatives:Doesn't work well in any way conceivable. I didn't expect much for the price, but it never ceased to disappoint. The pressure switches (only one of which kinda worked) are way far from being able to actually push. Then only the right side worked & you have to push it so hard that it barely even functions as a flashlight by itself. It takes so much pressure just to activate it for a split second that if it is on your pistol (Glock 19 for me) that it'll pop off the gun because it doesn't have enough spring tension vs force.I was amazed by this product! Truly.How does one simple flashlight fail in so many ways that it's even useless off of a weapon...which is it's intended purpose.Buy anything else. Go to the dollar store, look through the toy section, buy the cheapest kids flashlight you can find, then duct tape it to your weapon with little to no access to the on/off switch & you will have a better set up than this.Seriously shockingly terrible even by cheap super terrible Chinese flashlights go.I cannot stress how very not good this product is.Seller should issue a formal apology for selling it & Chinese manufacturer should commit industrial Seppuku (Google it).Buy anything else. Anything. Zip tie a Vic lighter to your pistol.Hope that helps.If you're still even thinking about it, then buy it. You'll at least get two batteries (one of which may work) for all your odd electronic devices that use the weird battery type it comes with.PS. Nothing else uses these batteries in the known universe. They didn't even get that right.

I don't typically leave reviews and I definitely do not like to leave negative ones, but I want to save someone else the trouble. I purchased 2 of these lights and both of them broke with in a couple of days specifically the notch that is meant to fit in between the picatinny rail just fell out of both of them. Also the quick detach spring is not strong enough to stay on the rail when firing 9mm caliber rounds. Save your money and look for another light that will be more reliable.

Received sight and opened package. Put in battery and tried to turn on light. Would not work, and then put in new battery and still would not operate. Called and complained and got refund. Would not purchase again at any price.

Great lighting for the price point. Mounts easily. The only suggestion I have is that an appropriate sized hex key needs to be included for tightening. Hunting around for one now. The light mounted easily on the weapon, but flew off during recoil after a dozen rounds. An included tool would be great.

Bought this light for a pistol, but it does not fit. The bar on top of the light is too thick to fit the groove in the glocks frame.Fits the rail on my AR fine.

Works great seems sturdy, don't know why everyone else was complaining

It is not using cr123a

Use on my glock 23 very good for the price
