I really feel like Covergirl has started trying way too hard but falling short. They make promises of their products and those promises aren't true for most people. Their All-Day Outlast line has disappointed me tremendously. If you sit around in air conditioning all day it might last but don't expect it to last in humidity or a night out dancing.
I will say that I am happy with Covergirl's eyeliners and some of their mascaras. They aren't anything special but they work well for me.
Other than that, they just seem to keep trying to put a twist on the same old products where major brands are coming out with brand new products that fit the current trends.
