Sis, this WORKS!!!
I honestly just purchased for the color but continue to buy this because it absolutely does what it says (which is rare these days). My nails are stronger and longer then they have been in years...I just cut them because they got too long. I get about 2 weeks out of it though I do use a top coat for extra shine and sealing. This coupled with good nutrition has done wonders. My biggest con is the bottle is tiny for the price and for my hands.
