Review (4/5): Surprisingly, it works
My hair is just a bit longer than shoulder-length, but it still worked for me. It will take some practice to get the hang of it, but even on my first try I got nice big curl/waves. On the second try I kept it in while I slept. It’s a little strange feeling if you’re a side sleeper. If you sleep on your back, it will work perfectly. I don’t won’t to always use heating tools because it damages the ends. This is a nice alternative.
