This might be the first one! It just one month before it broke. My bro, age 16 180 cm. height 70 kg. of weight he just take full smash flick the wrist and then racket head and the shaft was separated! and head flew over the net to the opposite side.
That's a depressing sight Expensive racquets aren't supposed to behave like that! If you post its serial number and the manufacturer's code (on the cone), the racquet's authenticity could be verified.
This broken one, VTZ is claimed from the last broken Arc FB at Yonex Center on January 2014. They recommend that the Arc FB not suitable for a strong man or big smash so they recommended the best and most powerful racket for him.
Yes, the racquet is genuine. However, the advice is not. The Yonex chap who gave you the advice was speaking through his behind Carsten Mogensen (75kg, 185cm), who is taller and heavier than your brother, is using the Yonex ArcSaber FB. So is Mohammed Ahsan who, undoubtedly, has a heavy smash.
I already claim and got the new one from Yonex Thailand in just one day! Thank you so much for all staff.
the racquet made for Pro players are not what for sale in the market, they have IP code for International Players so the quality may be different.
