I am a huge fan of CHI products and even though they are pricey they are worth it. My hair stylist recommended that I purchase this iron as I have super crazy, insanely thick, ethnic hair. I need to use professional quality hair products and CHI seems to be the best out there for my hair. I got the one inch iron as some of my hair is short and it allows me to get even the shortest pieces of hair straight. The way the iron is designed it has a safety feature so the sides are curved to help protect the heated ceramic plates which allows me to get closer to the roots which gets my hair to lay even more flat and I rarely burn myself. The ceramic on the plates hasn't cracked or worn down except in one super tiny spot but it doesn't make a difference. Other irons that I have used extensively, the ceramic has worn down and even cracked at times which gets strands of hairs trapped and breaks them or will get clogged up with product and will burn and make the iron smoke up and smell terrible. Also I find this iron gets much hotter than any other iron I have used which actually makes my hair stay straighter longer. I used to have to flat iron my hair every other day or every day if muggy out. Even if the weather is muggy or if I go to the gym I only have to straighten my hair 2 times per week 3 if I have a special event where I have to look perfect. My straightening time has also been cut down which is fabulous. It used to take about an hour to straighten my hair and now it takes about 25-30 minutes. I only have to run the iron over my hair 1-2 times as opposed to 4-6 times in super small sections. I still section my hair but the heat really penetrates and I can use thicker sections with less swipes to straighten my hair. This has reduced the amount of breakage that I have as well. I use the CHI heat protection spray before using the iron and the combination of the two makes my hair super soft and silky and STRAIGHT! You will not regret purchasing this iron and it comes with a warranty in the box as well so don't worry about it breaking. They are durable and crafted for your ease and protection so you don't have to worry at all. Effectiveness I have crazy hair and this iron manages to get it straight and super silky soft it works wonderful!! I bought it on recommendation from my stylist as he uses it for all of his clients with hair like mine or for clients with shorter hair that needs to be straightened. It doesn't work as well when I do it as opposed to him but it still comes out great. It gets really hot which is key for unruly ethnic hair like mine - other irons can't get this hot and even under the extreme heat the ceramic stays intact which helps keep your hair smooth. Since it is so hot it can't be used on its own - you MUST use heat protection spray/oil so you don't injure your hair. This information comes in the box as well. Durability My Chi is indestructible! I have the world's thickest, craziest hair and I use and abuse my iron several times a week to straighten my hair and I have never had a problem with it. After a year of owning my chi the ceramic is still intact all I have is a tiny spot that has worn down a little but it is so small it makes zero difference.
