This is my absolute favorite mascara! The smudgeproof formula is discontinued in most stores so I was excited to see it offered on groupon and for a great price! This formula stays on all day - even through workouts - and doesn't smudge at all. It's amazing!!!! It washes off easily also with a bit of soap - comes off in pieces so don't get freaked out and think your lashes are coming off! - so it saves you a step of eye makeup remover. Try it!
