Some questions about hair rollers for hair straightening?

I have incredibly "fuzzy hair." Conair makes the best product. It is a flat dryer/ironer/straightener. It is the first thing in 40+ yrs to work on my hair. It is long and subject to humidity....instead of drying and then flatening my hair this does it all in one.....it is fantastic and YES IT DOES WORK. For the first time in my life I actually have shiny STRAIGHT HAIR. And it is inexpensive ($20)
