I was set to buy another replacement of SH Insta-Dri, but this caught my eye and I gave it a try...thinking maybe the Essie product would be better. Yeah...NO. I have tried it it with 3 different polishes, Essie, OPI and Hard Candy. Every time, I got cracks and wear after just a day or 2. At first I didn't make the connection to the new topcoat.....but the last straw was when I used over Essie Mademoiselle, within 24 hours I had BUBBLES pop up and the polish looks like it is lifting off my nails. Frankly, it would have been better with no topcoat at all. yes, it dries fast. That's about it. Back to Insta-Dri for me.
