I hope it's right ! Plus, I ask him to put a 25 tension for the string, the racket is still okay, and the guy said until 30, no problem, so I think it's genuine. Yeah I also think I got a good price.
25lbs is average and you have nothing to worry about. of course 30lbs will probably void your warranty but i've had people string it higher than 30 and the racket is perfectly fine. it's a great racket, enjoy!!!
