Pricey top coat, but it works really good. Dries super fast and leaves your nails looking really shiny. The only issue I had with it was that after I had used a little more than half of the bottle it began to get thick and gooey.
I really wanted to like it, but I think it just doesn't work with my nail chemistry. Seems like it never dried. I do use it for craft projects to seal colors in.
