This product gets 3 stars for color and opacity--it's gorgeous! I have the shade Maverick which goes well over top of a variety of lipsticks in my collection; anything from brown based shades through more deep plum shades. Unfortunately, the formula is terrible because it is super sticky. It also tingles and give a cold, pepperminty feeling to lips after putting it on (this doesn't bother me but some people are sensitive to that kind of thing). I am finishing my sample tube then looking for a different brand of gloss in a similar color.
