I cannot in good faith recommend this product. I have tried it with two different Colorstay Gel Envy nail polishes but the results were the same. It came out gooey, thick, application messy. It only lasted 2 days and I use gloves too clean and do dishes. I loved the nail polish though.

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.

I used the Gel Envy Diamond topcoat over my French manicure. I have a job where I'm constantly unpacking boxes and my nails get pretty beat up, but this top coat lasted longer than anything else I've tried. I don't generally like are long nail polishes as I find that they don't last, but this definitely is worth the extra cost!

This is a great top coat, but not as effective as a gel finish. You can get 3 to 4 days of nice looking nails, and it does provide a shiny finish.

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!
