Cracked LCD and backlight
Relatively smooth. Need to keep track of all the tiny screws on a magnet pad in some type of sequence to avoid losing them. Took about 1 hour from beginning to end. No scary moments. Actually easier than replacing only the LCD screen. Overall an excellent product, but a bit pricy.
Keep track of your screws on some sort of paper diagram or magnet. Make sure you seat the screwdriver well before turning screws to avoid stripping.
