I have to disagree with the other user. I've tried for YEARS (and I'm nearly 40) to grow my own long nails -- without any success. They've always been thin, dry and brittle. Well, with this top coat I am AMAZED at how strong my nails have become. For the first time in my life I HAVE LONG NAILS and they just last and last. The shine on the top coat is fabulous and I have found that it surpasses it's claim of lasting 10 days -- even when I only touch it up once or twice during the week. I LOVE THIS TOP COAT and will never buy any other kind every again!
Like all of Rimmel's polishes, this one is rather unfortunate. The lycra formulation claims up to 10 days of wear and a "super high shine finish". The finish the top coat gives to a set of polished nails is average (wears off rather quickly) and the top coat itself had some poor marks in the functionality department. If you're looking for a good top coat, my suggestion is to pay a few dollars more and pick up either Orly, OPI or Creative. Nothing benefits a manicure like a good top coat and this - is not a good top coat.
