This thing works great!
I have very thick and wavy shoulder length hair.  This thing definitely works!  I put it on after I get out of the shower and just keep it on for however long it takes me to dry off and put my pajamas on.  It is so nice not to have to worry about my hair tail falling down at an inopportune moment because everything stays put until you remove it.  I gave this only 4 stars because the button and loop needs to be bigger or a different color or material because it is difficult to locate them, especially with hands still wet from the shower.  I still haven't quite mastered how to do it perfectly but even with my imperfect operation, it still dries my hair in a jiff and it is much less frizzy!
