I have a racket with damage bumper after stringing at 龍x
At first, the old guy said that he had already used some plastic thing to protect it when stringing, hey, just see my photos.
Finally, he fused to say sorry and said he didn't notice my racket when I brought it to him and said that it might be my problem.
God, it is a brand new racket and I just played for one hour. I swear there is no any damge before I give it to him.
Anyway, I just want you know it is not a good shop. I will never never go there again.
