Overall Great Nailpolish...
I have a few bottles of this nail polish in my collection. In fact I have Gold Silk, Purple Rain, Hot Cocoa, and the French Whit Nail Tip Liner.
One of the greatest things about this polish is the thick curved brush. With this, you cover your nail in the polish in only one to two strokes. Some of the darker colors only need one coat as well. Like other people have said, I've also witnessed how quickly it dries and how long it lasts and the advertising his proven to be true; no gimmicks. The polish is so sheen that you hardly even need to use a topcoat.
My only complaint is the French White Nail Tip Liner in this collection. The brush is a skinny tip which is great when your polish is still brand new. Except when the polish starts to get old the polish will just start to ball on the end of the tip and you don't get as skinny of a line as you would've when it was still new. It's also not very effective if you have a very large tip to make, for example on your thumb nail. No matter how many coats you do, it's very liney due to the pointed tip. So the way I like to use it is to draw my initial curve with this polish and then fill it in with another white nail polish. But this doesn't mean it isn't great for a person with very short nails who wants to have a quick and easy french tip. It also works great for french tips on toenails. I just don't recommend it for filling in a large tip if you have long nails.
