I am giving e.l.f.'s liquid eyeliner a 4. It is easy to put on compared to other brands I've tried and goes on easily. I got mine from Target and it was very inexpensive. The problem I have with it is that it isn't very long lasting for me, however, I do have a tendency to rub my eyes, so that could be the problem. Also, I have noticed an odd smell that comes along with the eyeliner every time I buy it. I know it can't be because it is old, because it is always the same smell right when I first open it. Beside that, I find that the liner seems to rub of messily and can be a little difficult to remove. All in all, however I like what I get for the price it costs. I would recommend this product to people living on a budget who would like some easy on the wallet makeup.
