they are not authentic. They have the Apple logo and markings that suggest Apple made/designed products. Talking with and in writing from OWC staff they claim 100% authentic and direct from Apple.
So pretty much these are the definition of counterfeit.
counterfeit: adjective, made to look like the original of something, usually for dishonest or illegal purposes.
I'm not in a position to defend owc since I have never dealt with them.
Is it possible they are actually from Apple and have an agreement with Apple to make the font look different from units sold in retail Apple stores? I don't know.
In the end, I made a decision a long time ago not to buy from owc because of their prices.
