Blaser 515nm diode?

BLASER 515nm 30mw 3.8mm K type Green laser diode BLASER CO.,LTD.-in EL Products from Electronic Components & Supplies on Aliexpress.com

Anyone heard of these? Seems cheaper than the Osram.

This is the first I've seen this. It is still $73 for 30 mW
while the Osram is $99 for 50 mW. The math would
indicate a better $/mW with the Osram.

then for $85 AixiZ offers a 515nm that makes a nice 26mW BUT is a module-with driver so just add 3 to 4 vdc battery and it comes in the standard AixiZ module 12x 30 and that is inside a small module mount as seen in the pics posted and at AixiZ(under green lasers at aixiz.com) a simple build for the right hosts.
