I have nails that bend, chip, break and never grow. I've tried so many products and nothing has helped. The last time I was at the drug store I decided to give this a try. I like the shine it gives my nails and it does in fact make my nail tips stronger but it wears off by the end of the day. I have to keep re-applying it to my tips every day even though it says to apply once a day for 4 days. In short, it is pretty good and worth the money.
