I have long extremely frizzy hair. I either have to straighten my hair everyday or go around looking like I've stuck my finger in a light socket. This is no exaggeration. My hair has a mind of its own. I have owned several hair straighteners in the past but the Conair Infinity is by far the best one yet. It has multiple heat settings - from low to extremely high but for my hair it is always on the HOTTEST!! I use my Conair Infinity hair straightener every day. I wouldn't think of leaving home without straightening my hair with the Conair Infinity hair straightener first. It is made of quality construction - believe me I really put them to the test. I have used other models and have broken all of them until getting the Conair Infinity. It heats up quickly and does an excellent job. It is easy to use. I can go from outrageous hair to straight shiny locks in no time at all. My daughter uses it as well and loves it. It is the best. I don't know what I would do without the Conair Infinity.
