Review (1/5): Doesn’t work!
I left the product on for 20 minutes and nothing. I tried some nails with the top coat scraped off and others with the top coat still on and they were the same. Actually, the ones with the top coat still on where just as shiny as if nothing happened after 20 minutes. I tried scraping it off and no polish came off at all. I tried some nails with a thicker coat but it made no difference.
