L'ange will always be my favorite brand for curling tools. The Flex still gives great curls'"though I almost feel like the "tight" setting gave me looser curls, and the "loose" setting gave me tighter ones! Either way, the curls looked great. Two downsides to the Flex are the high-pitched fan noise and the occasional finger burns. With the Classic, you can touch it anywhere'"it's super safe, especially for someone just learning how to curl their hair. I have the Classic Duo and Classic Grande, and the fans on both of those are much quieter'"more of a soft hum. The Flex has a noticeably high-pitched sound in comparison. Still, I highly recommend any of these tools!
