I love milani. I have cyberspace (blue) and hi-res (purple) and they are beautiful. Everytime I wear them I get compliments saying how pretty the color is and asking what it is. You only need two coats at most so one bottle lasts forever. I dont know what the staying power is because polish never lasts long on my nails anyway but I love this stuff . Ive been meaning to get more colors but I havent gotten around to it yet.
