When I first tried the nail polish and the diamond top coat I didn't really notice the difference this baby made. Until I tried it a second time and saw that it added a bit of a sparkle to the nail. Goodey! A real goodie was that I got it for free when I purchased a gel envy color.
Now I'm not sure if this top coat is responsible for the chip and tear free guarantee or not. But it makes my nails sparkle and that's good. I'm not one for top coats and base coats and over coats and under coats. I like thing to be simple, but what I like is that it speeds up the drying process by an entire life-time and that gives me time to enjoy the finer things in life.
