Review (5/5): This stuff actually works!
I don't usually review a product (unless I'm especially ticked off). However the reviews on this are mixed so I thought I would help swing them to the positive. It comes with no instructions, so I looked to Amazon for help with that. I did not sand off the top coat of my gel/French manicure. I just put it on the nails of my left hand and gave it about 8 to 10 minutes. Then I used polish remover to get rid of the blue gel. You do need a metal cuticle pusher to scrape off the rest of the polish. I will probably use this before I go to the salon (if we ever get to do that again!), just to save the time of the foil wraps. My only disappointment is that my nails are so thin from such a long term use of the salon gel manicures. No implications against this product though, just saying...get ready. I'm quite pleased with this purchase and it didn't break the bank, by any means. Give it a shot!
