For someone like me who is clueless about how to style hair, these are a dream come true. If curling irons have always made you look like abstract art, and not in a good way, and you've resigned yourself to having the hairstyle of an 11-year-old for the rest of your life, don't be dis"tress"ed any longer!
The Conair Ion Shine rollers are very easy to use, take very little time (five to 10 minutes to heat, a few minutes to roll, and about 10 minutes running around the house looking like Medusa while they set) and the results are gorgeous, natural-looking and last all day.
I am told by my hairdresser that they won't damage hair, either. I've been using them for months and my fine hair (that's meant as an adjective, not a self-congratulation) is as healthy as can be.
The only negative, and it's a minor one, is that it's a bit cumbersome if you have to transport it from room to room, and if you don't grab it firmly by the base you can snap off the dome (or at least I can). But this shouldn't be an issue in general.
(Incidentally, I wound up buying another set for everyday use and put the one with the snapped lid in the new set's box. I keep it in my suitcase as my travel set.)
In response to a comment by Carrie, you're correct; my review was of the Conair Ion Shine Instant Heat Hairsetter, which is predominantly cornflower blue in color and, apparently, discontinued. Amazon switched out products on this page!
