Cool 20mw 635nm diodes! On fleabay!

I found some 20mw 635nm diodes on eBay!
I know recently there has been some buzz on these higher than 5mw 635 diodes, and I have been watching around trying to snag some.

Unfortunately it is a ten pack and I only want one, maybe two.
Cost is $175 buy it now for 10 diodes. I am unsure if more than one ten-pack is available.

Also the specs on the page are kinda sketchy but I think this I just cause they are a Chinese vendor that came into some stock and they don't know much about lasers. The only thing that really makes me suspicious is under "absolute maximum ratings" For optical output power it says 650 mw. I am not sure what that's all about but I don't like it.

10 Units x 635nm 20mw TO18 5.6mm Laser Diodes | eBay

So if anybody wants them all there they are cause I'm not currently able/willing to drop 175 for ten diodes when I only need one. Just thought I would inform you guys of a pretty decent opportunity.

Or if somebody is willing to make a small GB(once again not sure If only one 10-pack is available or if there is more) I will buy one from you, and there are probably a few others that will take one too.

Just be sure you all know that just like these other possible 635 group buys lately there is a risk these won't be up to spec, or even be 635nm before anybody starts any kind of GB.

Sketchy Chinese laser diodes are sketchy.

These might only reach 635nm when chilled.

Very true.

I became very cautious when i saw "650 mw"
but i would still be willing to spend 20 or so dollars for one probably.
