How to spot a fake Oyaide plug

Just for people’s edification: the easiest way to spot a fake Oyaide plug is to look at the plug body and see if there is a metal insert which the screw that holds the body and plug together is threaded into

if you look at the link and scroll down to the first picture and look at the right hand side of it you will see, especially through the clear and blue plugs, the insert in question right above the model number.

If you see those inserts no matter what you were told the plug is a fake. Hope this helps
