8 minutes to complete, using only a screw driver and credit card, once every three or four years, is definitely "annoying". But, I'd still say it's also "pretty easy" (I never said "easy"). My reference frame may be different than yours.

Have you actually done it? Mine were 15" MacBooks, not 13" like in the video – maybe that makes a difference. It took me about 20 minutes. In the video the outer two battery packs just pop up without much resistance – that is not how it was in my case. It needed lots of acetone and patience and it was a messy process. I also had to apply quite a lot of force and was worried I might tear a battery pack open in the process (they were already swollen and looked like they might explode any moment).

The noname replacement batteries also have nowhere near the same capacity that the Apple batteries had originally.
