Throw away the others!
I agree with the others - this product is the best one.  A salon owner recommended it to me after I had acrylic nails removed, and my nails were pretty and strong again within a few short weeks.  I have tried other products for many years, but even the OPI products and Nailtiques don't compare to this.  I love how this product leaves my nails shiny, too.  Try it - it's worth every penny.
