I have been fixing Macs since I was a kid and well before the genius bar was around. I used pbfixit.com, macfixit.com, and now this current site. Additionally, my father and I had to do a lot of laptop and device repairs without guides. A general thanks to everyone for the guides on this site, however, I urge most of you to be careful because there are tons of mistakes and most people don't listen when you point them out. Woot.
