Wrong thing was to open pre-order until the item was polished, anyways I think it is worth waiting. just very irritating this "few days" and "next week" thing from Winwing, that is not a serious approach, if they have issues should apologize and tell us what is going on. it not 10$ or 100$ item to act like that. a lot of people will think twice before purchasing this set, as problems with a warranty may be more serious.
As I understand reviewers cannot confirm the quality and materials of the item, winwing claims it is steel and aluminum durable materials, I hope it is true and not some kind of cheap aloe that will break soon.
