FEELER: ML520G71 635nm diodes

So I'm interested in selling some 635nm diodes. I have this link to a batch of 100 of them:

New import Mitsubishi ML520G71 638nm 300mW Red Laserdiode-in Diodes from Electronic Components & Supplies on Aliexpress.com

They run at about 300mW.

Of course I would probably have a 20 piece buffer just in case of issues. What do you think of this idea? It probably wont be a group buy, probably a presale. I just want to hear your opinion on this.

I wouldn't thrust the seller with 0.0% Positive feedback. The price is way too low for $2.65 each.

Unless there is some guarantee / assurance , or a reputable member/vet is involved i wouldnt spend a dime otherwise! Sounds a deal too good to be true!

Alright, thank you sir
