It's interesting that most of the author's claims about quality (and reasoning to not buy a non-Apple brand power supply) boils down to "look at all the extra stuff on the circuit board in the apple power supply". Surely not everything Apple put in the charger was absolutely required, and that also doesn't mean someone else couldn't deliver the same quality with less components.

The main take away message though is the proper isolation you get in the Apple one.

And that's the actual conclusion of the author. Don't buy the other one, not because the extra stuff in the Apple one is worth it but because the others generally cut a corner too far. ( or worded differently, if you don't have the skills to assess the safety of the design from the cheap one, buy the Apple one )
