This is worth the money! It works great and fast, you dont have to hold it on your hair in each section but for a moment or two to get perfect waves. Section out your hair, work from the bottom layers up. For long hair I recommend starting from a out eye level and down, dont get too close to your roots unless you want a lot of volume. If you have long hair but want a more subtle wave, start from your jawbone and down. I do recommend doing this on dry hair. There is only one heat setting and it is very hot.
