This product worked surprisingly well. I used it as an undercoat and a topcoat with a cheap dollar store nail polish. Usually the polish chips within the first day. This product kept my nail polish intact for a week, with only 1 small chip by the end. (However I feel this was due to the fact that I was active, carrying camping items and swimming daily). The price was fair and I was extremely happy with the results considering how tough I was on it. I鈥檇 definitely recommend and purchase again in the future.
