Review on 🔒 3M Privacy Filter for 13" MacBook Air: Preserve Your Confidentiality with Pfnap002 by Andrew Gomez

This is listed by the manufacturer as suitable for HP Specter but is 1/2 cm to wide. Not worth trying to get a real one that fits, so I won't be returning it. I just cut off the edge and called it done. Not entirely surprised as I have a similar 3M filter for my Surface and had to trim it to fit the dock as it didn't have proper cut outs for it. Hopefully they would do better, they fit the laptops they sell them for them, but it looks like they're just being very general and hoping for the best (or people doing what I did and trimming). The non-3M is significantly cheaper and may be a better buy since you'll still have to trim it to fit. 3M should be better at getting it right out of the gate.
