This is odd.. I have a 1mW rated green laser and it works extremely well for pointing out stars for 2-3 people around me. With dark adapted eyes you can see the laser beam at almost right angles.
I once tested the power output with a light meter and it is definitely below 1mW (about .7mW without new batteries).
I dont know of how much this one cost as I got it as a present.. but you do have to be careful with cheap ones. They can have poor focus and may just be lying about their output. It would be best if you could test it with a light meter.
