Let me start by saying - as someone who spends 8+ hours daily staring at screens, the 92.1% blue light blocking claim immediately caught my attention. After two weeks of testing, here's my real-world experience with these protectors.

The Good: The installation frame is GENIUS - even my tech-challenged roommate installed it bubble-free on first try (we celebrated with pizza). The 9H hardness survived an accidental drop when my dog wagged his tail too enthusiastically near my coffee table. Most impressively, I noticed significantly less eye strain during late-night TikTok binges - the slight yellow tint (subtler than competitors) actually feels soothing.

The Not-So-Good: While the glass is thick, one protector cracked mysteriously in my bag (possibly from keys?). The coverage doesn't extend fully to iPhone edges if you use bulky cases - my Spigen case lifts a corner slightly. Also, the English typo on packaging ('forbearance' instead of 'forgiveness') gave me a chuckle but doesn't affect functionality.

Pro Tip: Watch their installation video at 0.75x speed - the alignment trick using the dynamic island cutout works perfectly! For $10-12 per pack, you're getting bona fide blue light protection that outperforms those $30 'gaming' variants I've tried.

Final Verdict: If you're sensitive to blue light or want hassle-free installation, this delivers. Just don't expect case compatibility with OtterBox-level armor cases. My eyes say thank you every night!
