I'm not sure if I got the same brush as the other reviewers but I have had a polarizing experience. It's thick like other reviews say, but the latter part is not true. It doesn't accurately apply. Its so thick and course that you can hear the bristles swoosh across your lid. I even tried to layer up the eyeliner on it to see if that would help because I really hate to go through the trouble returning one brush but it just made it even more inaccurate and thick.
tl;dr The short, rough bristles glide with resistance over the lid. Ouch! Will be returning.
