Watch out if you're expecting a Surefire X400 based on the store page. This is a no name cheap replica "with Surefire markings". I guess the price is a hint, if you know the value of a real one (Which i didn't). The laser adjustment barely works, only allowing a couple of CM of adjustment in both elevation and windage. The adjustment screw falls of before the beam is even close to the pistol's point of aim. Even after adjusting the windage to it's maximum distance, it is still more than 30CM away from my 0 at a 3 meter distance. I'm guessing if i was sighting at a longer distance, the laser would be on the wall to the left instead of where i'm actually aiming. Completely useless laser. A 15$ no-name laser i got on Amazon is more adjustable and can actually be used. At least the flashlight works i guess. And the unit itself looks good visually so this won't be a 1 star, but this should not cost more than 30$.
