I have used this product for 2 weeks to give it a try and done my nails 4 times. Not because I do my nails that often, but because it CHIPS!!!!! I even did a double layer for a clear finish and it lasted 5 hours. As a top coat on Ruffian nail polish it lasted 2 days. Highly dissappointed and will look into returning it. Worst top coat I ever tried.
Regardless of how careful I think I am, I always manage to smudge a nail or two within about an hour of painting my nails... until I started using this top coat!! I highly recommend this product!
