I was quite skeptical about this product, but I do have to say that I like it. The tint does require practice and trial and error. When I did it for my sister, it looked like sharpie brows and that was a disaster. It's hard to use to get my brows even and I learned that the front part of the brows should be applied lightly and sparingly to avoid the boxy brows look. The negative thing I noticed that after a few days, the color could turn orange and did not last as long as I expected. Overall, not bad, but I personally need to experiment with it more. (Mine was in gray brown btw. Probably most natural for anyone with virgin dark hair)
