Before I started using this product I was always buying different kinds of nail strengtheners that were just average. Now I use this and only this! This stuff is awesome and it definitely works for me! Using this product has made my nails really strong. I use it as my base and top coat and it works great. When I wear gel on my nails I have a tendency to peel it off after two weeks and this has made my nails really weak and brittle (they even started splitting! this never happens!) but using this product has helped repair them.
