I’ve gotten pretty good at applying scratch protection sheets, with my phone and iPads etc. so this was familiar to me. The set of two screen protectors includes the usual cleaner wipes, dust cloth, positioning aide stickers, and squeegee. The biggest thing to know, if you’re not familiar with this type of thing, is to remove every spec of dust immediately before application. The “dust magnet stickers” are essential. Even if you don’t see any, there will be dust or lint. Use the sticker diligently and you will be less likely to have problems. Mine went on just perfectly, and seem to have no effect on functionality. The one thing is that they do reflect light with a purplish sheen, and that seems odd. It doesn’t seem to be an anti reflection or anti glare coating, just a characteristic of the material. I’m used to it now, so I don’t mind. YMMV. I did not get the instrument cluster screen protector because I never touch it. I don’t have the passenger screen in my ST GTS. I just got the center console upper and lower screen kit.
