I have been using max factor 2000 calorie mascara for years and absolutely loved it, but being a woman I couldn't keep myself away from trying something different and ordered this a few weeks ago. On first use the thing I noticed the most was the size of the brush. It's big. And difficult to work with; I never understood the logic that a bigger brush would equal bigger lashes, it's nothing to with how long the bristles are! Whilst the finish is relatively volumised and long lashes, the formula is just not up to it. It stays put if you don't have watery eyes and don't have anything touch you face throughout the day but this crumbles a fair amount, so I end up teary and having to touch them which only leads to smudging and more crumbling. I would probably be a bigger fan of this mascara if it stayed put and had a smaller brush but if you're looking for that just go for max factor 2000 calorie.
