Not sure about these, but I ordered a triwing kit off Amazon and it stripped all my screws. It left little bits of metallic shavings on the screwdriver itself so I had to use a bit if super glue on the casing. Ended up buying a new grey pair and my custom shells are on display.
Seen those and there not 100% need. The oem ones work just fine. If your broke then yea buying that one will work. I cant say if its easy or not. I make custom joycons and been tearing things down for years so its all easy to me
