My eyes water like crazy, I've tried every "waterproof" eyeliner and this one is by far my favorite because it actually stays put!!!
I've used this eye liner for YEARS. If your looking for a product that lasts all day, doesn't smudge, water proof..then this is it! I will say it's almost too good because it is sometimes hard to get off. I went camping for 3 days and it stayed on the whole trip. The last day it was a little dull but still looked pretty dam good! It's a felt tip as well so for me it's really easy to apply with compared to other liquid liners!
Although this product smudges at times and isn't necessarily waterproof, it has longevity. I prefer the Wet and wild over Covergirl and L'oreal. Applying their eyeliners was a hassle and half way through the day the liners were gone from my eyelids. I have a horrible habit of rubbing my eyes.
