Hi all, I just bought a new racket and it makes a clicking or ticking noise from the cone when I swing especially when I hold it like a knife. Actually, I have done some research on that and most of the answer is the noise comes from the loosen cones. I found that many posts suggest claiming a warranty. Anyhow, I have not found any post telling their story after that. Did they get a new racket? Did Yonex reject this claim? So, I just want to know that do Yonex normally consider this loosen cones as the manufacturer's fault and their claim got approve? I just what to hear it from someone so that I feel confident to make a claim.
