I truly believe Kiss Me makes the best eyeliners! I've lost count of how many brown eyeliner products I've used from them. The brush tip doesn't bend and has good firmness, so it applies smoothly. The brown color looks natural too. The staying power is great, and even when it starts to fade after a while, it only slightly disappears at the tail ends without smudging or flaking!
There aren't really any drawbacks. Maybe just that it's a liquid eyeliner, so you need to concentrate when applying it!
