I like this because it's basically like using a khoki (felt tip marker) to draw on your face :D I'm not the most precise when it comes to applying makeup but this makes it way easier. It also lasts quite a while, and I haven't noticed any smudging - which is huge for me as I have super oily eyelids that melt everything that comes near it. One issue I have is that the tip sometimes starts to get... straggly (not sure if that's the right word) So what I do is just cut a small part of the tip off to make it sharp again. It IS quite pricey but the lasting results make it worth it.
