This is the first skin that I have ever applied with a hot air dryer, and it certainly helps form the skin to the back cover. However, the skin isn't perfect in it's coverage of the back. I lined up the camera, flash, and speaker holes perfectly. What was left was slightly off for the outer edge of the skin. The right side was too close to the edge, while there was still some white showing on the left side. It's not too bad since its barely a millimeter off, but it is definitely something that I noticed.
The rest of the skin went on smoothly, but I was surprised to notice that mine did not come with the home button piece. I most likely wouldn't have kept the piece on anyway depending on if it caused issues with the fingerprint scanner since I use it daily. The sides have stayed in place pretty well over the past few days without any movement or peeling of the edges. Another thing that is slightly off is the top edge of the screen cover. I have the speaker, camera, and sensors aligned properly, but the notification LED cutout is a little lower than where the light is.
The skin itself isn't too thick, but it does make swiping the fingerprint sensor a tiny bit more difficult. I was even able to put a case back on over the skin, albeit with a little difficulty. Overall, I am quite satisfied with the skin, and look forward to more skin choices from EXO skins in the future. Here's hoping this review fixes the slight errors on the back, as well as possibly introducing more wood grain choices.
