I used three coats here. The formula is decent--a little goopy, but nothing terrible. I used a glue basecoat with Firecracker because I'm sure removal would be not so fun otherwise. Aside from that, this is easily my favorite Studio M polish I've tried! It would make a fabulous polish for a night out or any other time you want to be sure your nails will get noticed. There is some crazy sparkle going on here! I love it!
As far as I know, Firecracker is a Studio M original and not a Color Club re-package (the brands are owned by the same company and share colors a lot), so if you want it, get thee--or a swap buddy--to a Meijer!
