I found this on ebay and was wondering what the likely-hood of it actually working with a m140 445nm laser diode putting out 2W-2.14W?

I don't know anything about optics but from what i'm told you have 2 beams go in and 1 goes through while the other gets reflected 90 degrees and joins the other laser and you get like 50% more power?..?
It seems sketchy because i see some going for 40-100 dollars and this is 14 dollars from ebay... any thoughts?
