Apple's self service repair is an absolute joke and its only purpose is to exist on paper while deterring everybody away. They will ship a pelican case of factory level equipment to your house, which you need to rent ($49/week) and pay a massive deposit for ($1200). Companies that actually want users to be able to repair their stuff will write at-home repair guides and sell minimal kits similar to what's on iFixit (e.g. tell the user to heat adhesive with their hair dryer rather than a $500 piece of commercial repair equipment)
