This is a great nail product . It helps strengthen weak , thin,brittle nails. It also helps fill ridges in the nails. It lasts an average of about a week and then begins chipping. It’s worth it for the price

This Sally Hansen miracle strengthener helped my nails to stay hard and not crack or break during the day! It drys fast and provides a nice shine, however when I use it as a base coat, it chips off a bit faster than a normal or long lasting base coat. It depends on the polish, but I prefer to use this a few days before a manicure for best results, to make sure polish stays on my nails! Works best with other Sally Hansen polishes!

This is a good product. It's not as good as their original nail hardener. But this is a nail strengthener. I mean I guess my nails were stronger. But I prefer the nail hardener.
