Excellent guide. Replaced my SuperDrive in 1.5 hours with no issues.

Although this guide a difficulty rating I wasn't sure how long it would take a fairly adept novice to complete the R&R of the display. I took my time and did the tear down in 1 hour. I separated the fasteners by placing each section on a loop of tape above the work. The replacement of the new display took me about 2 hours. As the guide says it was just the tear down in reverse. Things that added to the replacement were getting the first 2 screws aligned and in place; re-routing the antenna and camera cables and making sure the camera cable socket connector was in correctly. The good news is it worked on the first power-up. Great guide.
