445nm 450nm Blue Line Module Generator Projector Diode for Positioning Laser Alignment Locator for Wood Stone Fabric Cutting Laser Swamp DC5V(Blue Line)

Used it for a laser swamp and it was awesome!

I bought this to use on my walkway with a fog machine. The laser works well with the fog for about 6 feet, then diminishes. Took a little trial and error, but I found that you have to use a fog chiller to make low laying fog and set the laser line just above the fog layer. It works well enough for my application. I just wouldn't expect it to work on large lawn unless you have multiple lasers, which is what I'll do next year. Shipping was fast and It was the only one that could be shipped to me before haloween.

Perfect for our Halloween smoke hallway. Mounted it low and with the fog machine added sick visuals!

I like the color and it is certainly bright. But it will not focus down to create the beam effect in fog or haze which was the single reason why I bought it. I don't know if the lens is faulty or if this is a design to keep the beam more diffused. It acts more like a wash than a laser. It will project a line on the wall or ground, but that is not what I wanted from it.

Easy to use! Very bright laser! When used with a fog machine it looks like water! Perfect for Halloween!

I was hoping the product would have created the actual effect I was aiming for, but unfortunately the power wasn't strong enough to do so. I had a 7'-0" wide by 12'-0" long area that was filled with low-lying fog and the laser beam only reached about 3'-0" into the fog and no further. I was disappointed by its poor performance. Perhaps this vendor has a much more powerful option? My suggestion is to heed what I shared about the square footage area and how it did not meet my expectations.

This one’s good. The last one they got did not focus down to a small being in the color was lacking. This one is good

It's a moderately powered laser (about 500mw) that died on me after 3 uses in less than 90 days. There's no way to reach the seller so don't bother
