My original screen cracked. The Apple store would have cost $1250 for flat rate repair/replacement post-warranty and most vendors were selling screens for 30-60% more than IFIXIT was charging.
It went very and well under an hour of time from start to finish.
The best tip in the directions was to separate and label the screws you remove accordingly and in order. DO be careful when removing the Keyboard from the base due to the inner cable attachment. Great photo directions already in the system to follow along! Thanks IFIXIT team!
