I am OBSESSED with Zoya nail polish.  As a long time OPI and Essie polish lover, I came across Zoya through pinterest.  Sloane was my first color used and it is a beautiful color.  I find the polish to last as long as the competitors, if not an extra day (though that could be because I'm trying a different base-coat).  I also find that Zoya is not as thick as the others and I find it easier to manage.
