Great but inconsistent [SEP] I gave this three stars because it’s 50 50. I use it on some colors and it completely changes the color in a week.  It doesn’t matter if it’s a light color or a dark color it comes back weird.  If it doesn’t change the color this stuff is unbelievable. It comes back in two weeks with a very high shine. Also I  apply it over my pink and whites and it doesn’t yellow at all.  It’s good for people who don’t like the blue tint on their pink and whites. They just want a clear topcoat.  The topcoat doesn’t always apply to every gel polish. I noticed on china glaze it leaves gaps. Almost like oil and water. The basecoat is unbelievable you won’t have a problem with that.
