I bought this on a whim. I wanted a new base coat because the midwest winter had been hard on my nails and hands. The polish is good on its on, or as a base to color. It lasts the average length of time (3-5 days), as any other base with the exception of a few drug store brands that don't last very long. It does not stain my nails, which is a huge plus. It works with a multitude of different polish brands. I will repurchase it, as I feel it's a little gentler on my nails.
