one thing that is very important to note about these 30mw lasers. THERE IS NO IR FILTER. took a picture with my webcam of teh beam off side and all I get is a white flash of IR. Not a clue if these are newwish lasers or not. the price is nice there's no doubt. BUT be aware. Lots of IR comin from it!
This picture is taken with the beam about 3" above the webcam
I bought 3 of these over Christmas and they're fantastic.
All 3 of them work at approximately the same power and they were so damn cheap. Even cheaper than DX.
Perhaps I was lucky, but the quality control on these units seems to be more consistent than those at DX. Very good output on these cheap units. I'd recommend.
Yuppers. Nice units with the exception of no IR filter. I ended up getting the two so I could give one to a cute girl that works at radio shack. hehe (how often do you find a girl that's as much into electronics as you are) She likes hers very much and even got a hug from her. so it was a good investment as far as I'm concerned.
