I just bought a (should be new) lining aeronaut 7000 racket from an online shop that guarantee its product to be 100% original and provide full money back guarantee for its fake rackets. However, when I received it, the authentication code is scratched and when I try to check the code it does not registered in the lining website. I try to weight it and it weight 85g (official lining says 84+-1g). So, as far as I checked the finishing, gourmets and weight it looks fine and genuine to me, yet I'm not sure since this is the first time I bought a lining racket. So, is it a genuine new racket with code problem(maybe I inserted the number in the wrong website) or is it a genuine secondhand racket or is it a fake racket? Can anyone help me? Thx before.
