The iOpener works surprisingly well. It does involve patience, I think I applied it a good 4 or 5 times at least to get the adhesive to give way. It was confusing where to put the new adhesive and I had to remove part of a piece around the camera in order to allow the fingerprint sensor to reattach. It would be nice if it were more clear where the adhesive went, nonetheless, I firmly believe that this is a good kit and I only broke one of the 6 picks. Definitely a moderate fix, but possible with some patience. It took me about 3-4 hours total with breaks. I spent a LOT of time using alcohol, picks and the spudger in order to remove the old adhesive. It did not matter that much in the end though.
