Just want to clarify with those who have experience getting their sets swop for issues after the 14 days period. I understand if one do so within the 14 days period, it had be a new retail set. However, afterwhich if you swop, the replaced set will be come in a form of a different box which I was told. Anyone have any idea whats the difference between that and a refurbished set? I was also told that they are not refurbished.
