I tried this out a while back and was really disappointed as it didn't do what it claimed.
I found it fine on level 1 for enhanced but natural looking looking lashes but on 2 and 3 it was horrible to use. On the higher levels it clumped terribly and just looked terrible. It didn't really give volume as such just stuck all my lashes together. I didn't have a problem with this smudging but it definitely got flaky at the end of the day and I often had a couple of little black flecks on my face (not an attractive look). It was nothing terrible just not a good mascara for me.
I would not recommend this mascara nor will I repurchase it as it is in no way one of the better mascara's I have tried and is not much cheaper either.
