I have the need for waterproof mascara because I go to the gym with it still on, and I absolutely hate endind up with that black residue under my eye, and I need it to stay on the whole day no matter what happens. What I generally don´t like about waterproof mascara is the time and effort you put on to remove it. I previously used L´oreal Telescopic Waterproof which is very hard to remove with my silicone based two-phased remover. This claims to be waterproof and easy to remove with non-waterproof makeup remover. I find that it is somewhat goopy and clumpy, but that´s probably because I´m not used to volumizing mascara, and I end up having to remove the excess, which is sort of time consuming. I found out that it doesn´t come off with my regular remover, but it comes off easily with the waterproof remover. I said that I wouldn´t buy it again, not because I don´t like it, but probably because I´d like to try something else, and I certainly like it best than my L´oreal Telescopic.
