I have a MacBook Pro that I have had for about 4 years, which for me is a record. It just won't die. And the pieces that do die, places likeifixit make it so easy to replace. My SuperDrive decided it would no longer read DVD's or DVD-DL's. Ordered one, and 10 minutes later the problem was solved! And it lives on...
With the right tools, it was a 10 minute swap. Easy peasy!
Not nearly as hard as you may think. If you're not familiar with taking a MacBook Pro apart, just follow the step by steps, be careful with the screws, and take your time.
