Things they say you need:
Skillshots inside info on what you really need:
Small Phillips Screwdriver. Bonus if you have an electric drill (for unscrewing only).
Anything small and plastic for prying. I used an old credit card.
Fine Point Tweezers
Electric Range
Small cup to put screws and small parts
Large cup to put larger electrical pieces
CLEAN surface. There's a lot of adhesive you want to preserve.
Use the electric range if you don't have a heat gun. Works the same. Don't drop it. I'm sure an oven could also work if you have a gas range.
The stock adhesive was still VERY sticky. No additional adhesive was necessary.
No special pry tools. Anything plastic and rigid will work.
Yep, smashed the snot out of it.
Now it's as good as new. Only had one screw left over. That's a lot better than after I finish working on my car.
These things work using the effects of quantum tunneling. Not bad for $99 shipped.
