I've tried everything on my hard to curl hair. Hot rollers, curling irons, curling wands etc... I use top of the line brands, and my curls never lasted, if I got a curl at all!! I ordered this- not expecting much, but I was hopeful. It takes about 30 minutes to get the hang of it. Be sure your hair is not tangled, small amounts only. The good news is it doesn't work if you try too much hair. It gives a perfect curl with hardly any effort!! Lasts until you wash it! I love it !! If you decide to try it, spend some time & practice. Don't give up- easier than hot rollers and those deadly wands!! No burned fingers!!
