Neopack Anti-Glare Frame for MacBook Air 13" M1, M2, M3, M4 Series & MacBook Air 13.6" (Clear, 1-Pc)

Easy to put on, works effectively to cut glare, but also reduces resolution / clarity as a side effect.Attaches securely on top but the sides and bottom have nothing to hold, so if MacBook is tilted the anti glare screen hangs, which also makes it prone to dust getting in between this and the MacBook screen.Also where the screen touches the laptop glass, in some places it tends to form an oily looking stain/patch from contact visible at an angle but which goes away when lifted.Overall cuts glare and adds some protection. just wish it had a way to stick at the bottom and temporary stains/patches could be avoided.
