I am a girl who for some reason can't keep nail polish on. Even on my toes. I used to think I was weird, now I don't have to be. Chip skip really works for me. I use it on my toes before polish and a topcoat. It really is worth the price because it WORKS!! For my nails, I still had to use the chip skip plus another (non-OPI) product to get polish to bond to my fingernails longer than an evening. I am now happy to say I can wear polish on both my hands and feet because of the aid of this product. It goes on super quick (I'm not sure on the technicalities of it, but it would seem that it is taking off the natural oils from my nails to get the polish to adhere better). So once you put it on, it is like it evaporates in a second. You may think - what DID I pay for? Well actually - it's the product just doing its job! Don't panic. Move on and polish away. Top coat seals the deal and you are set for an anti-chip adventure!
