I will give ya the short version - as I've written a long, detailed on this post previously.

Last Dec, I bought a green laser for about $85 on Ebay - it came from Hong Kong. On Ar15.com - someone wrote a positive review of it on their PS90 - so I gave it a shot.

The problem was that it was TOO bright. These things are more powerful than their claimed 5 mW power - they are usually 10 mW. To import them, I think it needs to be 5 mW max, and no one is really checking these things, I guess. Anyway - it lit up a dark room like a flashlight almost. Plus, U could see the actual beam. And, if looking at the dot any closer than 25 feet, your eyes hurt. It was TOO damn bright,a nd really useless indoors.

Now, in sunlight, U could see the beam over 100 yards away. And, at night, it was rated for over 1000 yards. I tried it at about 800 yards and easily saw the beam.

It makes a good toy at the 100 yard outdoor range. But, I wanted a laser for indoor use - to be able to shoot it at 7-10 yards w/o using the optic, which is sighted in at 50 yards (my eotech). As the PS90 doesn't have tons of rail space, and I wanted a flashlight mounted - I did not have room for a flashlight, a red laser AND a green laser.

I ended up selling the green laser - someone WANTED it for outdoor, 100 yard use. And, he was aware of my cautions.

I really didn't think the thing was too safe. I did some research on lasers after I noted that it hurt my eyes to look at the beam on the wall. I didn't think it was worth the risk of owning it - as you could damage your eyes with a powerful laser w/o having someone shine it directly into your eye.

Now, as far as the price point - these cheaper lasers will probably not handle the recoil that more expensive ones can. Now, the PS90 kicks almost like a 22. But, I have seen neg reviews of these things when places on an Ar15 or something with more recoil than a PS90.

Also - U won't really know how powerful these things are - as they aren't necessarily marked with the proper wattage.

Boy, good question.

Plus, my Surefire laser tends to "eat" batteries I let in it....even when in cold storage. I take them out every time after the range to prevent them from being drained.

I wonder if this can be said for this laser, does it drain batteries like my surefire? Are their other issues like shoddy construction? bad water seal? Poor distance of projection?

I wonder too.

Edit: Well, there you go. I guess we have our answer.

Very interesting. Yeah, I guess it really isn't worth the risk it carries for the price.

Thank you for the abridged version and shedding some good light on this topic.

Well, I was disappointed over the whole thing. If I had been putting it on an AR - I may have kept it since I would have had the rail space for an outdor toy. Of course, I never would have ordered it for a weapon with that amt of recoil or more.

Anyway - if ya did want to buy an ebay green laser - there are 2 models out there. There is an easier one that allowed for adjustments with hex screws. I've read mixed stuff about that particular model U linked to.

But, for safety reasons, I would pass.

The biggest problem w/the cheapie green lasers is durability/ruggedness. A red laser comes from a single diode emitter which is solid state and pretty rugged. However, there is no solid state single green emitter (AFAIK) so a red laser is used w/the beam passing through two frequency changing filters to end up green (which is something like 30x more visible to the human eye than red). Any misalignment between the beam & filters and you lose it entirely so sufficient ruggedness to maintain this alignment is critical.

I do agree the laser max / sure fire etc are built better
but there is also a much larger profit margin in those for dealers and mfg's then the cheap ones

The new green laser max costs around $400 retail - that's just totally absurd!
