I love using the opi dip powders. Works great and stays on for 2-3 weeks. The clear setting powder is a must, but follow OPI's videos and put it on last so you don't file through your dip colors and waste product. I love that I can buy the dip colors to match the nail polish I already have. Keep in mind that it does take longer to do your nails but it lasts for long enough to be with it. Great product!
