This is my first time using the OPI Infinite Shine collection. I'm really loving the staying power and the color of this polish. It's perfect for St. Patrick's Day! I was really disappointed with the brush. I much prefer the wider, paddle-shaped brushes on Essie Gel Couture. I found that I needed a lot more swipes of the brush to get the nail covered, and the polish would sometimes start to dry before I had a chance to work. Granted, I'm still a nail novice, but I ordered some replacement brushes to see if I can solve the issue!
