I was looking on ebay, and currently, there is a seller, radioheady2000, selling lots of Yonex AT series racquets, example:
However, as the beginning of this thread, the first post, this seller used to sell FAKE racquets, such as MP-300, so I am not sure if those AT800 racquets are genuine since he used to be a fake racquet seller.
All his current photos are far and not clear, with masking on the serial numbers, so there is no clear evidence on the racquets he is selling now. It’s hard to tell if those are real or not.
His prices are too good to seem to be true, too. The price is so close to dealer’s invoice, and I am wondering if he can survive from selling like this if those racquets are real ones.
Just to point out this in case people are wondering the same thing as I do now.
