First attempt was very passable. I was very impressed and confident that my next application would be even better. Wow! Second go it looked like I'd been to my usual salon. I've even done infills which again was extremely effective. Definitely lasts 3 weeks. My nails are lovely and strong. Just follow the process and don't rush it. Removal takes some time but well worth taking care so as not to damage your nails. My nails were in good condition after removal too
