I have 4, good as any other, they all peel eventually on real nails, but last as well as any other. The only 2 MAC ploishes I had that wore off in hours literally, was from the snowgirl collection. They had this awesoem metallic color, but wore off within an hour or two, peeled right off. Was weary to try more as those were my first mac ploishes, but so far have 4 doing good with those, must have been that one collections formula(old square bottle too).
