This is two coats of Holographic Hero, with no topcoat or basecoat.
Application takes a little practice. Like many other holos, it can drag a little if you're not careful, so you need a decent amount of polish on the brush. After that though, this is fine - brush is nice, formula is smooth and dries quickly.
This is a nice shiny silver holo. In indirect light it's not special, just a pretty silver. But in the sunshine - wow, it's so pretty!
Gosh Holographic Hero is available (if you're lucky!) in Superdrug for £4.99 and the label now clearly says 'One night wear for Holographic Lovers' so you can't complain when it chips. Not that you'd wear holo for a night out, because you need the sun to make it work. Oh well.
I'll let you know how it wears!
