I have one. It doesn't work very well for me, unfortunately. But, my hair is much longer than yours is. I'm not sure if the difference in length would be a plus for you. But, I couldn't use the 'fingers' in my roots or I got wonky, bent curls.
Boo! LOL! I have much better luck with my bowl diffuser and a low wattage blow dryer.
