Sally Hansen Insta-Ombre Swatches & Review

Hi fellow nail polish lovers!!
Today, I have four polishes to share with you from Sally Hansen's Insta-Ombre line (see press review here).

In order to get an ombre look, you're supposed to apply a coat on the entire nail.  Next, you are supposed to apply a coat from the middle to the tip.  Finally, you add a third coat to the tip of the nail.

These polishes definitely should be layered.  I thought that I'd be able to wear them on their own, but it didn't build up the way I expected.  They're some pretty glitters.
What do you guys think of these?
