Our read on it
This is a privacy protector listed as fitting one device, sold singly. Everything below is taken from the seller's own listing and from our catalogue — we have not fitted this one ourselves, and we say so rather than implying otherwise.
In its favour: an oleophobic coating is declared, which is what stops the surface smearing permanently after a fortnight.
Not stated in the listing: no alignment frame is mentioned, so expect to fit it by eye.
The listing advertises 9H hardness. That figure is the pencil hardness scale and essentially every tempered glass protector claims it, so treat it as table stakes rather than a reason to choose this one.
Claims made by the seller
- 【EXACT FIT FOR MacBook Air 15.3" M2/M3/M4/M5 — Model A3448 A3241 A3114 A2941】 — Custom laser-cut for MacBook Air 15 inch (2023–2026) with M2/M3/M4/M5 Chip & Touch ID. NOT for MacBook Pro 14/16" or Air 13.6"/13.3". Check the "Axxxx" number on the bottom of your laptop before ordering to avoid wrong size.
- 【30° MICRO-LOUVER ANTI-SPY — Keep Your Data PRIVATE】 — Advanced microlouver technology narrows the visible angle to ±30°. Your screen stays crystal clear when viewed straight-on, but darkens from side angles—keeping passwords, emails & confidential files hidden from prying eyes in cafés, co-working spaces, airplanes & open offices.
