It just goes to show ya that everyone has their own likes and dislikes..the last review on Prolash...I recently tried it and returned it. It didn't stay on and I wasn't impressed. I just recently purchased "X" and that I like for volume but no length...does stay all day.I am picky about mascaras!Sometimes I put on Maybelline's Lash Discovery first because you can get every lash and them put MAC on top to "hold" it until the waterproof version of Lash Discovery comes out.
