Told a student of mine that replacing the USB port would be a piece of cake. I have 6 different kinds of USB-C receptacles in my supplies drawers, thought for sure I'd be able to impress them. Turns out I was wrong. the USB port they use has pins buried in places it's impossible to get to. They wrap the whole socket with a metal cover, trying to give the appearance that it's "reinforced", but when you get that cover off you can clearly see these are designed to fail. No way to reflow these with hot air or hotplate. So frustrating!
