If it's over 10mW on eBay, don't buy it. It's a waste of money.

That there looks like your typical eBayser. I know it says there 'don't be fooled by cheap imitation lasers' well that IS a cheap imitation laser

heh i figured that lol. I already got 2 phr803 in aixis modules on the way much rather that! how mw should one of these put out with a fixed 100ma rkcstr driver? and would a 9v battery be good for this?

For a blu-ray? Uh, 100ma would give you about 80-100mW. Can't tell for sure since it depends on the diode and stuff, that's why we need laser power meters And a 9V battery would be fine for that kind of driver
