This mascara might not be bad for naturally curved lashes. But as I am using a lash curler everyday to prep up my otherwise straight eyelashes I need good waterproof mascara to hold it all up. And this just does not do. My lashes uncurl on the spot (so I have reason to think it is not all that waterproof either).

So I only use it for my lower lashes. The small brush does come handy on them it's less likely to brush my lower eyelid.
