I purchased this as a gift for my grandparents. My grandfather had been complaining about his nail becoming brittle and breaking. My grandmother was trying to paint his nails with strengthener to help but it wasn't doing the trick. I purchased this to see if it would be better. After a couple of weeks of use they both use it and love it. They said their nails are doing great. They also use Solar Oil everyday on the cuticles to help keep the cuticles and nail bed hydrated and healthy.
