Bobbi Brown Pressed Bronzer?

Hey, im currently looking into the bobbi brown pressed bronzer powder. its like 33 dollars at macy's and i wana get it. does it have good coverage? does it give good color? i read that it has NO shimmer, i DONT want shimmer AT ALL. anyways, i do spray tan i have self tanners and i get tan so should i get the shade that would match my spray/gel tan? or should i get the shade that would be my natural skin color? how long does it last? anything else? thanks
