Let me start by saying this eyeliner is a BEAST when it comes to longevity. I wore it through a 12-hour workday, a sweaty gym session, and even forgot to remove it before showering - and guess what? It was still there! The waterproof claim isn't just marketing fluff.

The application is buttery smooth - almost too smooth. While this makes for effortless gliding, beginners might find it tricky to control. I learned the hard way that less pressure = better results. The rich brown shade (though slightly darker than expected) gives that perfect 'my-eyes-but-better' definition.

Now, the elephant in the room: sharpening this thing is like defusing a bomb. No matter how careful I was, chunks would break off until I discovered the Revlon universal sharpener trick (thank you fellow reviewers!). Pro tip: store it in the freezer for 15 minutes before sharpening.

For my fellow hooded-eye/hooded-eye-gang: rejoice! Zero transfer onto my upper lid - a miracle considering most liners turn me into a raccoon by lunchtime. However, waterline application stung slightly, making me question if this is truly ophthalmologist-tested.

The staying power does come at a removal cost. My usual micellar water needed backup from an oil cleanser. Worth it? Absolutely - unless you're the type who falls asleep with makeup on regularly.

Final verdict: When you can get past the sharpening drama (and maybe invest in a good sharpener), this outperforms liners triple its price. Just don't expect delicate Japanese-brush-precision points - embrace the slightly blunt, lived-in look!
