Because the hot tool is automatic, it promises perfect curls or waves every time (as long as your hair is at least four inches long) and according to its fans on TikTok, it's much easier than a traditional curling iron or wand. I got the CHI Spin and Curl Ceramic Rotating Curler ($100) in the rose gold colour but it also comes in a newer version called the Volcanic Lava Ceramic Pro Spin and Curl ($130), which is supposed to be healthier on the hair.
