Are they taking good care of the D60 HF's because I went to fordham yesterday and I saw a bunch of D60HF's and they all looked used and dirty and some had alot of sot on the back then every LFSA I saw they had super clean and they looked as if they just got them so are they really are they taking good care of the D60HF's and putting them aside and only caring about the LFSA
