Supposed to be a powerful laser, with more power than other traditional green lasers, but I have tried it and it is soooo weak compared to my other 5mW green laser. Bad product, stay away....

This laser is pretty impressive for 25 bucks. It's pretty solid and has some weight to it. I don't know if it actually outputs 30mW, but it's pretty darn bright on fresh batteries. I've never owned a green laser before, so I can't say how it compares to other advertised power levels. The beam is clearly visible in mid air in a dark room and was visible for at least 50ft up in the air outside at night with street lights on all over the place and plenty of city light polution up in the sky. It does dim somewhat after it runs for a few minutes but not bad. The lasing crystals used in green lasers are sensitive to heat, as is the infrared pumping diode. The heatsinking is probably not really up to the power output, esp considering it's packed into a rubber wrapped pen. It does get warm to the touch (but throw it in the freezer for 2 min and it's insanely bright again). Considering the price, though, I don't see this as a big drawback. The $200 ones are expensive for a reason. Only complaint I can really come up with is the batteries that came with it didn't last very long, but I was expecting that before I even ordered it. Energizer lithiums are the best.
Buy it! It's an awesome gadget!

I bought this just for fun, and it is good quality BRIGTHT green laser. Mine doesn't dim, the button isn't wearing out, and it is far brighter than a red laser that my daughter has. I've shined it on houses and stuff over a half mile away with no problem. Much past that the laser doesn't carry, tho, because of all the stuff in the air. I'm not a scientist or nothing, but if you are looking for an inexpensive bright green laser pointer, this is the one for you!

I just got my laser today and i am amazed with it. The lighting is great and you are able to see the beam at night or when it is dark

!Great Laser!
!Thanks HDE!!

I bought this laser for my son and he has had a blast with it. I teach a Sunday evening class at church and he took everyone outside and showed how it pointed at stars. We don't have a lot of experience with laser pointers but we have been very satisfied with this one. It does use up batteries pretty quickly though.
