Bought another controller for the kids to play together (rather than stealing mine!) - the One S version with bluetooth (model 1708).
However, immediately upon opening the thing felt off - just not quite 100%. I would know, I have spent thousands of hours with genuine controllers in hand.
Upon closer inspection, the plastic just isn't perfect. The thumbsticks have mold lines. The warranty sticker isn't stuck down. I weighed it compared to the genuine 1708 model and it is 18g lighter… not much seemingly, but thats about 8% overall and certainly not a rounding error.
Obviously I'll put a refund claim in via eBay, and I'll chat with eBay support tomorrow about what else to do - any other advice?
Take photos of the defects as proof.
If the seller asks you to send it back, refuse. As I understand, it's against the law to mail counterfeit products in Australia, so you wouldn't want to open yourself to liability!
You should get a 100% refund, ebay won't do anything to prevent the seller continuing on with their scam though.
