[Ekstasy]

I've never really had a problem with most mascaras I've used before, but let's see... most recently I've used Covergirl Lash Exact and Urban Decay's Big Fatty Mascara.
Love the brush on Lash Exact - no need to comb through after and I've never had problems with smudging.
Big Fatty Mascara is also a favorite of mine just because it does its job, plus comes packaged with a wicked name. :P
