Love this top coat. Love the extra shine it adds. But what I love most of all is the applicator - how come other nail polishes don't have the double brush that Revlon has put on their Colorstay Gel Envy products. After using the applicator of this product which is double the width of other polishes and curved at the base I find I can't put up with the applicators on my other polishes! I use this Top coat as a nice coat to my nails without the polish when I know I won't have time for reapplying for a few days. It gives my nails a nice shine.

Wow, le meilleur topcoat qyue j'ai essayé. Lorsque je mets du vernis sur les ongles de mes mains, il dure en temps normal 2 jours. Avec ce topcoat merveilleux, ma manicure a duré facilement 4-5 jours sans retouches! Excellent produit!!!!

The "Diamond Top Coat" is a great, thin consistency that dries shiny and quick. Only downside- the bottle is black so you won't be able to tell how much you've used.

This is a great product, gives a high gloss finish. I used it both with Gel Envy Nail Enamel, and with another nail polish: same great result. Last a long, long time. Love it!
