Shane,
Without doubt Festool USA provides the best service and support in the history of hand operated tools. So far none of mine has required a return trip to Lebanon for service. Between my dealers and the End User classes we know how to maintain our Festools to factory-spec.
I deliberately did not single out any particular chain. Even my preferred dealers need to use part time employees. People can and have made mistakes.
However, it is a major blunder to sell as new a used tool missing components of the set. Since it is the USA dealer who handles the registration, we can only hope that happened in the mentioned cases. Had all the paper work for the sale of those tools been done by part time employees without direct supervision, then there is a huge management problem with that dealer.
Trusting Festool USA as I do, I am sure this situation will be resolved fairly to everyone's satisfaction.
Of course since my own first copy of a new Festool has been pre-ordered, long before it is available for pick-up I have researched the packing list, so I can be sure the carton/Systainer has the full collection of parts. I use so many sheets of abrasives I am not sure I would count them, but an open package would to be be suspicious enough I would resolve the issue before leaving the dealer.
Although I have never purchased anything from a Woodcraft store, largely because none are convenient to me, one of their employees was a fellow participant in an End User class. That is a fellow who really knows fine woodworking, so his customers will receive excellent coaching.
