I don't know any of the people who have had issues with QSC, the difference between you and I is that I support them being treated right. Mostly because their stories are very believable given the evidence put forth.
What we're still struggling to establish is why you so adamantly defend QSC's actions and support them with your entire being. I have purchased products from so many labs over the years, almost all of them have treated me reasonably well. Of the ones that treated me great, if they had a major issue that QSC has, you would never see me dive into the thread to support scamming or floaters or otherwise.
Consumers should look out for consumers, that's how we all get treated as well as possible. Your behaviour is irrational. If you're a satisfied customer of QSC then you should be happy with people holding them accountable for their wrongdoings as that puts pressure on them to keep doing a good job. When you support scamming and waving away of large production issues like floaters in their gear, you're giving them the greenlight to treat you like shit on your next order.
Unless you expect to get freebies, kickbacks, or financial compensation for your time here. Which I'm not sure is against the rules, so do your thing. You're just going to be labelled appropriately.
