Bro, alert Suyama San to this matter. Wear and tear should not account to chipping of shell.As your unit is still under warranty, it is ridiculous for Jaben to charge you reshell or repair. Please keep us updated here. All the best to you. No choice? I hope the same thing do not happen to your incoming 435. If the same thing happens, I hope you can also say NO CHOICE BUT TO PAY TO REPAIR OR IF NEGLIGIBLE, JUST CONTINUE USING. You are downright irresponsible for this post.
