I won’t watch the video as I cannot watch animated things for too long. But honestly, I think it is hard to identify broken parts and they might get the wrong thing, therefore different quotes.

I would like to hear about their reaction when the mistake becomes clear. Issuing the costs for the correct replacement/repair and wave the wrong one would be the correct thing to do.

But actually, I don’t think this is an Apple exclusive problem. Some companies are better, some are worse, but I couldn’t repair any modern laptop by myself without fearing to break anything, be it Huawei, Chuwi or Apple.
