Recently i brought my brand new arc saber 11 to a reputable stringer aka haribito method, my racket frame got damage by the stringing clamping tools at all 4 corners, when you feel the racket frame there is a few hump and worst at 10 o'clock there is some dent. The stringer invited me to his home and show me the machine and explain to me his grandmother stories trying to push away all the faults he created. Then he came to a solution to help me sell away the racket, i was like ok this is a good solution. After that he called me saying he got many rackets to string and wanted me to take back my damage racket so not to mess up their racks, i met him and he starting to tell me his grandmother stories again showing me pics of possible situations where the frame might get damage. I was like ok now you going to push all the faults to me. Conclusion he blame the tag surround the racket frame causes the whole damage. Note: My racket is brand new, did a thorough check at the frames before sending for stringing. I hope all BC'ers becareful of this stringer, and till now i am very disappointed with him.
