I ordered Salvo, Vantage & Mayhem (or rather Recoil, Headshot & Fracas!) and they arrived earlier this week. VERY happy with them! They're so cool!!
They took paint very well and look amazing. I washed them before painting them with Games Workshop paints.
The only one I have slight issues with is Salvo. He doesn't hold together too well and I had a hell of a time putting his neck/joint in place. Everything on him pops off too easily, too. Having said that, he looks great with Perceptor!
I highly recommend these figures and will definitely be getting more.
