These are amazing, just like every other Conair hot rollers I've ever used! Takes practice to physically roll each section of hair & pin/clip each roller in place, but once you've mastered it, the rollers do the rest of the dirty work for you. My hair always looks like I've just stepped out of a salon after each & every use. I've got thick, frizzy hair, but you'd know after I use these. My hair always looks smooth, frizz-free, and the ends of my hair fall down into a slight curl, giving the appearance of healthy ends opposed to my usual split ends. The only downside for me is the hard plastic lid- I always seem to crack it. But if you take good care of your set, they should last you years- I've had my sets for an average of 5+ years EACH!
