You have to be patient with this product. I have been using Kill Brow for years and it is the only Tattoo Brow product I have had luck with. I have little to no brows so unfortunately I do not use the "brush" side of the product. It does stain the skin fairly quickly so you need to know where you want your brows when you start. The pro's are it lasts all day without needing touch-up...I work where I sweat and it has never bled. I have blonde hair but darker brows, so I have used the dark brown, soft brown and grey brown...my favorite is grey brown believe it or not, it just tends to have the perfect coloring for brown in my opinion, but it is harder to find. So the other colors work well too. Con's are that sometimes it seems like it has dried up and not working, that could be on your first use or 5th or 30th, so do not think it is empty! Just keep putting pressure on it to work. Also I store mine upside down and it seems to be work more regularly, and I do get ALOT of use out of one pen. I put brows on almost daily and I can say 1 pen should last a couple months. So 4 stars just because of how it can be finicky about seeming dried up. I will continue to use this product as the pro's definitely out-weigh the con!!
