I think I must have been mad not use a base colour with this. That's six coats in the picture.
Pros: Super sparkly and a fairly unusual colour; I don't recall seeing a purple glitter before. I keep looking down at my nails and going "Oooooo shiny!" I'm also pretty sure I could fight crime with my bullet proof nails now (six coats!)
Cons: I have no idea how I'm going to get this off.
