Or are people not used to the delays with post from the 3rd world to the 1st world (to put it blunty)? And have unrealistic expectations (e.g. us/china delivery times?)?
Definitely not a scam, we've had north of 1600 orders (nearly 3000 individual units) since launch at the end of November. Many customers vent but never follow up publicly to say they've received their order, and we can't force people to do so. Still, we have had plenty of positive feedback (scattered amongst the trolling in the previous thread) as well as elsewhere (eg. https://forum.feathercoin.com/index.php?/topic/6014-openrigs-review-lulz/).
And yes, I don't think people are used to having to deal with a government department that takes weeks to do something simple, which only exacerbates a situation where people have unwittingly or begrudgingly chosen a slow shipping method and haven't read our delivery and returns policy. Over and above that, we have summer in the southern hemisphere in December, so our summer holidays are over December, so we had a holiday period where our fabrication slowed down drastically, and not everyone saw the holiday notice on the checkout page as they checked out. Finally, we have also made mistakes - tickets have slipped through the cracks, we had the incorrect shipping method description showing for an indeterminate amount of time early December, all of which can add up to a very frustrating experience for some customers.
We are working on bringing our timelines down, on pre-approval for outbound parcels, and on a smoother logistics chain, which should hopefully lead to a better experience for customers in future. I also think the negative feedback has a positive upside - customers that read this thread before ordering are more aware of the timelines, which is good news in light of the probability that they won't read our delivery and returns policy (despite having to tick a box during checkout to indicate they have read it and agree to it).
