I have pale, almost non-existent eyebrows.  Currently I've been using two different department store brands of "wind up" automatic pencils.  They're smooth going on but very easily break off, and are expensive for the amount of actual product inside the pencil.  I've also tried hard pencils but they don't apply easily and often the color is too dark or doesn't show up at all.  And the brow powders I've tried are difficult to get on light enough to not look like a drawn-on eyebrow, plus powder doesn't seem to last all day or stay on when swimming.  This micro pencil is the best of all of them:  goes on easily/smoothly in tiny strokes so it looks very natural, is a great color for me, stays on until you take it off, and you get the whole pencil plus sharpener.  It will last a long time and is a good value.  I highly recommend this product--it is my new holy grail of eyebrow pencils!!
