The Chi flat iron, well entire line of products are truely wonderful! I bought the 1 inch flat iron in March of 2006 and I still have it to this day (October 23, 2009). It's the ONLY hair straightener I use, will use, or reccommend. It has NEVER had any technical problems of any kind. I have extremely thick curly hair and one swipe of the Chi iron down my locks and it's straightened and shiny. It's definately worth the $100.00 you pay for them. I have also used their other hair products such as serums and such. They are also worth the money. I know the prices can be very intimidating, but if you have really thick frizzy hair this will be a God send to you. All the salons use them, next time you go in for a hair cut and style look on the henge of the flat iron...bet you it's says Chi. I can't stress how wonderful these products are. You can have hollywood looking hair in less than an hour!
