HG everyday eyeliner for me. Doesn't smudge lasts all day. Easy to apply and I haven't had any problems with the winding mechanism. I'm on my 5th one already.

pros:
DOESNT SMUDGE even when colorstay does on me! :D
nice smooth application
rich colour
retractable pen
has sharpener
cons:
doesn't stay on waterline, but i use it below anyway
the case is a tad too wide for the product as is can seem loose

I ran out of my Clinique Quickliner in Smoky Brown and decided to try something else for a change. This one just doesn't compare. It goes on smoothly and the shade itself is a nice basic quite dark brown. But the mechanism in the pen is poor. The liner just seems to go back inside the pen when applied. The linings also just seem to vanish during the day, not smudge though.
