A11. For Install: Start by placing your ROG Ally gaming device underneath the protective shell, then secure the top part. Please note that during installation, the protective shell might slightly obstruct the buttons, and you may need to apply some force to ensure a snug fit. For Remove: Begin by removing the protective cover from the top. It may be snug around the buttons, and you may need to exert some force to push it through the buttons. Then, remove the protective cover from the bottom.
