This $15.00 Pistol & Rifle Flashlight is pretty functional for the price. It installed easily and worked well. While it is not as sturdy feeling as a more expensive light, it shot well and was bright.
My main concern with the light is the switch. I killed the battery it came with the first night, as I accidentally switched the pistol light on.
I have reviewed Twod items before, and it is clear they are more for the airsoft market, I found this light worked on my 9mm pistol. I did not get a chance to use this on a rifle and I suspect that it would break, but to be fair that is only my assumption.
For $15 the Twod Pistol & Rifle Flashlight/QR/Compact 200 Lumen Flashlight is worth the money, but only for a gun that was not in heavy use.
I wrote about flashlight use in my original Understanding the Use of Handguns Book, I normally use a handheld flashlight in addition to my pistol as I am concerned about muzzling an innocent person while investigation nightly noises. I will redilly admit that a weapon mounted light is much easier to use.
I was offered this item in exchange for a review, but the above are my honest opinions.
