The stickers are thick and offer scratch resistance (why I bought them) I wiped the PS4 down with an alcohol wipe first. First, I applied the "top" sticker and heated it up a bit with a hair dryer so that the glue absorbed and bubbles formed. I've used them for a gaming session or two and no problems so far. Despite the preparation I made to apply the decal, I don't really think it will last long as the adhesive isn't that good. I will update. Edit: 9/24/16 I downgraded my original rating from four stars to 1 star due to 1 1/2 being unavailable. The problem is the glue. I've had two long gaming sessions of 5+ hours each and the glue holding the sticker is not working. If I could return a product I would. I don't expect this to last long and I think it will last less long with the PS4 oriented vertically rather than in the usual horizontal position.
