Maze Audio and other audiophile power cords

Hi, this is just a general observation, so nobody needs to get excited if I am mistaken.

We all know some sites are flooded with knock-off Oyaide plugs.   I know, since I suspect I am a victim of that too.   The plugs look almost identical, except the lack of an laser hologram sticker (which comes with a serial number, typically).   The screws are also of inferior quality --- they could get damaged after a few uses.   (granted, you'd only use the screws twice: once to loose them up for inserting the wires, once to tighten them up)

What troubles me somewhat is that the same sites are also flooded with audiophile power cords.   Many of such power cords look real nice.  8ga and reference designation and fancy SOTA technology description et al, but they also use the same suspected Oyaide knock off.

So my question is: Are they safe to purchase?  I am no fan of counterfeit.  If any part isn't genuine, I would not buy it.   (I don't mind inexpensive part, nor cloned designs, but I am pretty stubborn vs fakes)

Thanks.
