I am not a member of US eBay so I cannot do it.
But if somebody is you can go into this guy's feedback and there is a list of all the buyers who purchased the fake M300A. You can than click on their name and then click on contact member and just let them know they purchased a fake.

They not only will learn the truth but still have PayPal's 45days can claim against the seller.
If he has to start giving back money he might stop selling them.
I think we need to start doing something it's getting out of hand. Look at all the trouble it now causes with sellers on MP trying to sell SW02 tail caps. You could have a genuine SW02 but nobody wants to touch it unless it's still in the sealed bag because it's so hard to tell the difference when looking an image.
I hope one of you US guys can let these people know they have been ripped off by a fake.
cheers
