I found the Babyliss Twist Secret to be quite handy and easy to use. I tend to have a million fly aways at the front section of my hair and managed to hide it with the Babyliss Twist Secret :-)
I've tried using it when my hair was both curly and straight and found that it's not as visible/noticeable when I use it with my hair in curly mode. My 9 year old daughter will most likely be taking it over more so than I, as she's IN LOVE with it!
