So, I just received a link Band from an eBay seller, who advertised it as 100% authentic Apple. New open box. Box is authentic. Upon looking closely at them, I noticed that the etching on the inside of the butterfly clasp is missing, as well as the "assembled in China" etching on the lug. Plus, they don't feel very sturdy. The seller maintains that they are real, even without those etchings. For those of you who have these bands-does an absence of the etchings always indicate a fake?
