I purchased this product because I've been on a quest to find a great chip-proof top coat. I have used this only once, with other 'chip-free' products that usually work quite well, and am very disappointed. The usual brand of polish and chip-free basecoats usually last me a few days, at least. With only changing the top coat to this product, my nails were chipped within 12 hours. This was not worth the price.... at all.
