Review (5/5): very effective!
This stuff is pretty amazing! I've just recently discovered Seche Vite topcoat, which is a flipping MIRACLE product - but once the top of my polish became basically bullet-proof it became very clear that my only obstacle to a really long-lasting manicure was getting the damn stuff to actually stick to my natural nails. I asked the googlemachine for suggestions, and taDAH! this popped up.
Although I typically wear pale sheer pink on my hands so that wear and chips are less obvious, I put this to the test with a cute new hot pink polish... and I kept it on for 10 days! That is unheard of for my nails. Truly mind-blowing.
Good stuff! A very inexpensive and easy way to extend the wear of your nail polish.
