Problem with Ali is counterfeit city but I do use it for certain things, absolutely.
Also stocks of things there that bullshit USA rules prevent. Back when I was repairing macbooks and apple basically controlled the entire supply of TI usb c controllers? Like they existed and you could get the datasheet off mouser but they didn’t stock it bc apple literally bought 100% of the supply for years. But aliexpress and ebay had sellers that either pulled them from lines or harvested them from broken machines and reballed them. Considering this was how the machines charged it was the only way to un brick then
