It won't 100% replace heat styling tools but it is a great alternative.
Been seeing this system on the internet for awhile, finally caved into the pressure and tried it. For a non-heat way of curling hair it's pretty good! The smaller and tighter the section of hair you wrap determines how tight your curls get. I will say, as someone with naturally frizzy hair just leaving it wrapped uncovered makes the top of my hair poofy but if you slap a satin bonnet on it smooths everything out as the hair dries.
