I also returned it. Not that it was bad because it wasn't. It was creamy and smooth with a very high shine even without a top coat. But I compared it to Milani Black Magic, which is my go to black, and didn't see a difference. Check it out. I'm not wearing a top coat here.
Can you tell which is which? Black Magic is on the left and Boosh is on the right. I'll stick with Milani.
