I bought this mascara because it is waterproof- and that isn't a lie. I can shower and it will not come off, if I do not take it off before bed it will not come off- even if I shower before bed. This mascara stays on. This mascara is not as volumizing as colossal lash, but it smells better. I prefer this over colossal lash because it is not as fake looking, it gives nice definition. I would by this again when I am in need of a waterproof mascara.
