90% on ebay, amazon and even newegg are counterfeit anyway. :)
Not really, and I specifically wrote that I can get the same
counterfeit ones on eBay.
I perfectly know what the situation is.
As long as the thing works, it's good. Especially since this kind of hardware is getting rarer by day.
Would I suggest buying one while there are still original pieces going by decent prices (40-80 USD)? No.
Would I ever buy from AliExpress? No.
Would I force you to do the same? No.
Please keep us updated on its performance as time passes.
EDIT:
There are even "reviews" of x540-t2 nics from newegg with the missing yottamark.
Newegg is both a bad and dying platform, can't endorse using it.
