This eyeliner really has me on the fence. The negative of it is that its such a pain to apply and I find can be really mess and stick in your eyelashes. However the staying power is comparable to anything I've ever tried. I place a swatch on the back of my hand and, including have showers, its stayed for easily 5+ days. That is mental. I find that that it lasts on my oily lids and well is a great product apart from the application issues. For the price defiantly worth a purchase!
