i tried that too & didn't like it either. after the humidity this week, i had racoon eyes after 5 hours. not a good thing....
try DiorShow, Chanel Drama Lash or YSL Faux Cils if you like high-end mascaras. they all last long--no clumping, flaking, smudging or bleeding--after a long day. i like Za b/c it's cheap & i don't feel guilty tossing it after 3 months.
