Does a $15 Steam Deck Anti-Glare Screen Protection Work?

In this video, I am reviewing Magglass Tempered Glass Designed for Steam Deck Matte Screen Protector (7″ inch) Anti-Glare Full Coverage Guard, which is available on Amazon https://www.amazon.com/gp/product/B09X82S4XL/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
I got this last Black Friday for $14.99.
My impression:
Pros:
– Anti-glare works really great
– The screen will lose some level of clearness, but I think it’s at a tolerable level.
Cons:
– Slightly expensive compared to other screen protection covers
– You have to be extra careful and do your best to apply it perfectly at once. If you try re-attaching/adjusting as I did in the video, you will end up with corners that are no longer sticky. (They offered me a free replacement at the end, though)
