i think you will get advice from other BC forumer. My opinion is some are fake but there are a few genuine seller that is in that website. Good luck bro. my advise is buy from shop or fellow BC member here. cheers
Lelong is an online marketplace like eBay. There's a mix of original and fake rackets being offered there. It will be risky if you're not sure who are the trusted merchants. If the price is too good to be true, it is. And normally the fake racket sellers do not have an actual retail outlet.
