Any reviews or experiences that are positive or negative about the Undercover Mama?

FYI: I have to wear a bra out to feel supportive. I have the Bravado nursing tank from Target that I wear at home and love but would not feel comfortable just wearing that out (not enough support). I like my midsection being covered so this Undercover Mama idea sounds great in theory but I can't remember if I purchased it with my first and returned it or if that was something else.
