fears about new diode

+ I really want to create a topic about this diode-and I'm talking about them-they are NDB7B77
--
I have a little suspense because of the datasheet parameters because they are like an upgraded version of ndb7875-If this is the case, then the probability that they will reach 4W + is possible - they are sold on the civillaser for $ 70 and I bought one two weeks ago -But what I am worried about is that, according to DTR, this is a fake diode - but it's strange when so many websites have sold them - I need your opinion on this diode.:o:o
P/S:
I will build a mini laserpointer with this diode if they are really good:drool:
