How about the MacBook power adapter? https://www.apple.com/shop/product/MD506LL/A/apple-85w-magsafe-2-power-adapter-for-macbook-pro-with-retina-display with a 1.5 star rating on the apple site. Why? Because the cable is flimsy and breaks at the juncture with the power supply and at the computer. But does apple fix cables? Is the cable replaceable? Nope! You need to by a new $80 power supply because a cable they know very well frays easily breaks.
Want to fix it yourself? Well they glue the whole power supply together so you have to break it to open it to replace the cable. At least you can fairly easily splice a new cable on (that is if you consider work with a soldering iron and heat shrink tubing simple) if you are lucky enough to have the computer connection fail.
Same goes for iPhone charger. It is a terrible scam that they do quite deliberately, it is quite impossible they don’t know about the failings based on the rating on their own website.
