As in the name, it claims to provide a salon perfect finish up to 10 days, guaranteed. I guess that's possible if you have a lot of time to let your nails dry. I am rather impatient and find that once I finish painting my nails, I need a top coat that is shiny, dries fast, and sets my nail polish so I don't have to worry about smudges.
This top coat provides a nice shiny finish, however it takes a LONG time to dry. I applied this and let my nails dry for two hours, when I took a look all my nails were smudged with fingerprints all over. I removed the nail polish, repainted it again and within 10 minutes they were smudged again. Frustrated, I decided to cover the smudged nails with a glitter top coat and use a different top coat. The next day I went to look at my nails and they still felt a little soft, and not completely set. I am disappointed as with the money it took to purchase this, I could've easily bought another Sally Hansen brand top coat that I know works.
