The hair tool couldn't be any easier to use—just clamp a section of hair, press the "go" button, and the rotating barrel forms the perfect loose curl. You can even set the iron to spin left or right to ensure a natural variated look, or symmetrical defined waves. Potempa's celebrity clients Lea Michele and Mindy Kaling have already tweeted their praises for the tool, and because we love you, we're giving you an exclusive 20% discount off the $199 sticker price! Just enter the promo code BBB20 during checkout at sarahpotempa.com. The discount is valid only through May 17, so get shopping. See more Best Beauty Buys!
