The product packaging promises "long lasting smoky eyes in two simple steps" - those being "1) draw a thick line, and 2) blend with smudger". The pencil end glides well and goes on smoothly without having to exert too much pressure. The color I picked - Smoldering Violet - was a pretty purple and looked very close to the shade shown on the packaging, so no surprises there. Then I popped off the cap to the smudge applicator and began smudging the eyeliner... which resulted in basically erasing the entire line into my skin. The result was what I would expect my eyeliner to look after a full day of wear, when my makeup is almost all worn off. It didn't look "done" at all, and the color was almost non-existent. It looked just like a muddy smudge on my eyelid, as if I tested a product and then wiped it off with a tissue.
Needless to say, I'm pretty disappointed in this product. I'll still use the eyeliner part, but with a brush instead (FYI, Sonia Kashuk makes a great smudge brush for just $4.99) and I'll ditch the foam smudge applicator.
