I have been using this product for years. It is the only nail hardening product that I will buy because it is the only one that I believe works. It is a wonderful product. It makes your nails noticeably harder in just one week. It is totally clear and has a nice shine to it alone, or can be easily painted over with a colored polish. It does not peel off the way that some other brands of nail hardeners have a tendency to do. It is relatively chip resistant, but like with any nail product, over exposure to water or excessive application of hand cream will make it start to come off after a day or two. Regardless, it does it's job of hardening very well and can be easily re-applied if it does happen to chip or peel with time and wear. I have used other nail hardening products and none compare to this one. At about $9 a bottle it is a little bit pricey, but it's worth the money because it really works.
