Ever since a make-up artist used this on me for a photo shoot, I haven't used any other mascara. The brush is exactly the kind that works for me as it seperates lashes while applying a decent amount of mascara. I have found I prefer the "inmitable intense" over the "inmitable" because it is thicker and makes for a bit more dramatic lashes.
I have tried a number of different mascaras through the years and this one is my absolute favorite. It's not heavy, but yet adds length and fullness to my lashes without clumping.
