I'd been wanting to replace my China Glaze Blk-Bila-Bong for a while now, because I really liked it. So imagine my surprise when I got around to swatching this NYX Girls Robotic, and it looks like a dead on dupe! What a bonus. I don't have the two to compare, but I'm going to reference you to Helen's swatch of the China Glaze, so you can know what that looks like as well.
Robotic is a black jelly base loaded with teal metallic shimmer. It's an awesome vampy polish! I had to use three coats to get it to this level of opacity, but I didn't mind that - I actually anticipated it, a lot of times these types of dark jellies with shimmer require more than two coats.
Ahhh it just glows! This will probably not appeal to those of you who don't like dark polishes, but I LOVE polishes like this and I just crave them. They were my first loves, before I branched out into bright colors.
