Hi, My 13 yrs old son was hitting a forehand with a 5 months old Prince EXO3 Tour 100 during one of his recent tournaments and after the shot, the racquet frame on one side cracked open that he had to stop the during the point. He is not allowed and has never abused his racquet. He is sponsored junior player by Prince. So I called and told Prince about the racquet and they asked me to send it in. About a week later, I received a letter from Prince stating that they have completed their evaluation of the racquet and find no indications that the damage was the result of any manufacturers or materials defect. The damage appears to be the result of excessive wear to the head of the frame which weakened the racquets supporting structure. And they can not replace. I called and reason with Prince but that leads to nowhere. He used to play with Babolat AeroPro Drive GT for more than two years. The racquet's paint chipped away every where, the grommet worn out to the frame BUT that Babolat racquet never cracked or broken in anyway. It is still playable. Has anyone had any experience like this with this Prince Tour racquet? I certainly have lost confidence in Prince racquets. That is very poor quality made.
