OK…. So Ill qualify this with saying I was an apple tech for an independent company for about two years, and I now do it independently for my own company..

Did this in 20 minutes with my 9 year old holding parts so I can skip 14-33 as mentioned on the 2015 repair guide. Used a metal splurgier I got from newer tech long ago and my wife hairdryer. Its not as bad as some comments make it seem. I had set aside 1-2 hours but now I can enjoy my Friday bonus time and use my laptop away from a power cable. Good luck.
