dfk41 they will first try to help you via email/chat/video. But if the machine needs to be shipped to HK for repair they will cover everything. The machine itself is light, already comes with suitcase and they recommend to keep the cardbox. The machine has a transport mode so if you can still access that it will be easier to pack, but otherwise no problem.
I think in most cases the entire repair is less than 2 weeks (10 working days), which is insane.
One of the main reasons I sold my Bianca was it was out of warranty, and packing it for shipping to repair was a PITA. Not to mention the cost. Decent is really a peace of mind choice
