I love the way BB Long-Wear Gel Liner looks and the best part of all is that it is completely smudge proof, lasts all day and night and is completely waterproof (which I discovered when I got tossed into a pool). It lasts longer than MAC Fluidline (of which I own). This really is long-wearing and you need a heavy duty makeup remover to get it to even budge! Also, BB Gel Liner in Black Ink is a true dark black compared to MAC Fluidline in Blacktrack (which appears not as dark). Don't get me wrong I use my MAC Fluidline everyday and I trade it out for BB Gel Liner for special occasion since it's a little bit pricey. I have yet to try MUFE Aqua Cream Liner.
