Just got my first Deck (OLED hellltathayeah) and ordered two tempered glass screen protectors. First one- cleaned everything removed and span- dust bubbles. Second one- was misalligned just a fraction of a mm enough to get caught on the bezel edge and not adhere. Took it off and tried again- dust city. Two screen protectors binned.
I’m afraid to order anything else Deck related because my wife has already noticed my other Deck related purchases.
I have a 512gb lcd deck, never had the need for a glass protector. Everything is clean and great without, no scratches so far.
