I like that it's gentle on my eyes, but don't cut onions, cry, or have allergies when you wear it, because it will be gone. But, I recently had my eye royally jacked-up by trying to remove a way-too-effective waterproof eyeliner, so I had to use this one instead. It was gentle, and really easy to remove. I don't typically cry or tear up in my daily life, and if I have allergies I won't wear eyeliner at all, so something like this will usually suffice for me.
I do wish it were cheaper, though.
