The code makes sense. Also if you pay over $250 for a racquet from a store like badmintonalley you should be able to take a risk and say it's real.
It's legitimate. - The holographic sticker - solid grommet (this is patented by yonex) - laser engraved serial code - painting looks Matt and not crooked - handle has dark color green with tighter font size I've seen a fake one before and the serial was painted on, holographic sticker on the serial #, paint decal was flaky and crooked, lack stiffness, and racket head was more round. Badminton alley is located in sunnyvale / Cupertino area. It's a legitimate store. Again racket looks real and I would assume you got it from their limited batch they just reviewed from Yonex. Cheers
