Query: Waterproof? NOT!!!

The "waterproof" designation is a joke. This mascara starts "melting" off my lashes, causing my eyes to burn, within an hour or two. (I have no allergies to makeup.) It also flakes off like crazy, leaving little black pieces on the cheeks. Gives no fullness at all, unless you apply it 2-3 times, which makes it flake even worse. Goes on very wet and thin. Avon USED to make great waterproof mascaras, but they've all mysteriously disappeared from their product line in the last 6-9 months, which makes me exceedingly disappointed and frustrated.
