It is Great!
I've used it for about 3yrs and I use it as a base coat. I noticed that my regular nail polish last a lot longer than usual compare to any other base coat. Of course if I get my hand wet a lot or wash, it last less. But, I try to use gloves whenever is possible. The reason I give 4 stars is because when I'm half way or less than half way it starts to become sticky and stringy.
