First off, let me say this hanging-style blue light filter is a game-changer for my 8-hour workdays. The acrylic panel gives my 23.8" monitor a subtle amber tint that feels like switching from fluorescent to warm desk lighting - instantly more comfortable for marathon spreadsheet sessions.

Installation took 10 seconds: just peel the protective films (both sides!) and hook the top edge over my monitor. No adhesive means I can remove it for color-sensitive design work, though I rarely do - the 99% blue light reduction makes my eyes feel noticeably fresher after late-night gaming.

One surprise benefit? The matte surface cuts glare from my window better than my old monitor's coating. Though fair warning - the product description's size range seems optimistic. My coworker's 23" monitor left gaps at the edges, while my 24" fits like it was custom-made.

After three weeks, I'm buying a second one for my home setup. The included microfiber cloth is a nice touch for keeping fingerprints off this fingerprint magnet. Pro tip: angle it slightly downward to avoid accidentally pressing your monitor's power button!
