Review on 👁️ NUSIGN 14-inch Diagonal Anti Blue Light Blocking Screen Protector Panel for Laptop, Notebook, and Monitor - Enhanced Eye Protection from Harmful UV Rays - Widescreen Laptop Frame Hanging Type by Jeremy Miller

This thing broke as soon as I took it out of the box. I was holding it by the corner with one hand, and the corner I was holding just broke off. I held it between my fingers (like you're holding a plate of food, but it's not heavy at all, it's very light, it's just very fragile, like thin glass, not flexible at all), still I got it across the screen laid and it seems to work fine but as other reviews have said it will slip right away. If it was on your screen and you were walking while carrying your laptop I would see it just slide off before you could stop it and it would break if it fell. not sure how you could provide it. For $40 it didn't feel right as just taking it out of the box and holding it literally broke.
