I have tried many top coats and this was not the worst I have used but definitely not the best. My nails chipped in about a week, sometimes less. But the worst part was the air bubbles, I don't know if this has anything to do with the contents of the hardener itself but when I would put it on then put on nail polish, the polish would always bubble. I stopped using this after only a few uses.

I like to wear this alone and apply another coat

Love this it lives up to what it says.

It works great but it takes alittle longer to dry then some other brands.

It works great but goes on a little thick so it takes forever to set and dry

I really like sally hanse. this nail hardner works pretty good.

This is one of the better nail polish's. Doesn't seem to peel or crack off as fast as others.

I've used nail hardeners for many years but this product made my nails cracked, it looked like I had natural crackled nails. I had to wait for them to grow out so I could again use nail polish.
