Retro Repair Ali Express Unpacking 3

In this video, I’m unboxing a new batch of repair supplies and tools from AliExpress. I test out some Kingbo and Amtech flux, attempt to use solder-filled heat shrink connectors, and find a great source for ZX Spectrum keyboard connectors. From speakers to switches, I'm checking to see which of these budget finds are actually worth keeping on the workbench and which are a complete waste of money.
