I cracked the lens cover on some rocks while I was fishing. The phone was in my pocket. I dragged my feet in fixing it and ended up needing to replace the rear facing camera as well.
Very smooth. Instructions were clear and accurate.
The adhesive that comes stock is pretty good. Once you get a sense of the amount of resistance it gives, you can move forward confidently. The bezel for instance was fastened on pretty tightly with the tape and I was nervous about the amount of force required to move it. Just applied a little heat to the area and it started to give some. Then I knew it was just tape.
