The engraved serial/date code suggests that it is genuine but I can be wrong. Can you take a picture of the entire cone?
I'm not an NS expert,but price sounds fake to me.The serial looks correct though.So,which part in china did u bought it?Brand new or second hand?If it's a brand new,then it'll be fake,and if it's a second hand,the chance of it to be real were just 20%.635RMB for a NS9000...it's just so hard to be true.Cheapest price in the chinese net market is around 880rmb for a CH,n it's preety impossible for most of the foreigners to find out.The normal low price in the market for a brand new 9000 is around 1100rmb.Most ppl will sell their 2nd hand 9000 at around 700-900.. So,if urs r genuine,i might have to congratulate u..since not many ppl can get NS9000 at such a low price,esp if u're a foreigner.
I am not a foreigner though, I got it from a badminton friend of mine when i went back to vist china. Thanks for the answers, I just need to make sure it was genuine because i bought it from china and with all the fake rackets flying around one can not be too sure.
