I think QCD is fine, except that they weren't very helpful with my faulty iPad 3 when the speakers didn't work. Yes, it was beyond 1 year without AppleCare, but given it's wifi only (hence I don't bring it out) and I don't use a case with it, there weren't any sign of damage at all (read: mint), LCI not activated as well. They were reluctant to do anything for me to repair my iPad. I even offered to pay for a repair, but they said it wasn't possible (okay so that's something new I just learnt that iOS products aren't repaired, they're always refurbished). I kept insisting they do something for me (after all, they ARE the Apple Authorised Service Centre).
In the end they phoned Apple Australia hotline, and I restated my case with them and the CSO said he'd authorise a 1-for-1 replacement for a refurbished unit. It made my day.
